This geocache highlights the publicly accessible areas within buildings at the capitol offering opportunities to learn about the legislative process, view interesting exhibits and art, and access public resources. Throughout your search, you'll also encounter some interesting facts and stories about these locations.
While this geocache primarily aims to guide you through the Capitol's publicly accessible interiors, I understand that open hours may be restrictive (with only one location accessible on weekends). To ensure everyone can complete the course in one trip, I've included two options to solve the final. Even if a building is closed (due to hours, weekends, or holidays), you'll still be able to complete the cache. If you choose option 2, I encourage you to revisit and explore the indoor spaces another time if you can. The outdoor alternative also highlights interesting features you might enjoy checking out if time permits. Approximate locations of the keywords are listed as reference points in the waypoints menu. Photos have also been included to help locate the keyword locations in stage 1.

About West Capitol Campus:
Step back in time to the construction of the capitol complex 1912-1940.
In 1911, Washington State entrusted the design of its new capitol complex to two relatively unknown architects, Wilder and White. Their winning concept embraced the grandeur of the Beaux-Arts architecture movement, a style that elegantly blends elements of classical French, Greek, and Roman designs. The creation of this impressive State Capitol wasn't without its share of controversy, a story you can explore further through these links:
Since its initial construction, the original capitol complex has been expanded with the addition of several other buildings following the completion of the capitol complex in 1940.

Stage 1: Temple of Justice

Open 9:00AM - 4:00PM M-F
N 47° 02.205′ W 122° 54.290
Note: Please be aware that all visitors entering the Temple of Justice building will need to go through a quick security screening. This involves emptying your pockets, passing through a metal detector, and allowing a visual inspection of any bags you may have. Weapons (including anything with a knife blade) are not allowed in state buildings.
Although the posted coordinates for this multi are at the south steps to the building there is another entrance that is ADA accessible at Reference Point R1 N 47° 02.217′ W 122° 54.259′
Discover More Than Just the Court:
While the Temple of Justice is renowned as the home of the Washington Supreme Court, it also houses a valuable resource for everyone: the Washington State Law Library. This library welcomes the general public, and Washington State residents can even borrow books and other materials after completing registration to become a borrower (details on the Library Borrowing Page).
The Law Library's mission is to: "Promote reliable access to legal information and provide expert legal reference assistance."
As a patron of the Law Library, you can access a range of helpful services:
- Assistance from reference personnel for basic inquiries and locating materials.
- Borrowing privileges for WA State residents, including books, eBooks, and other media (see the Online Public Access Catalog).
- Access to valuable legal research databases.
- Inter-library loan services.
Facts and Features of the Temple of Justice:
Beyond its role as the home of the State Supreme Court, the Temple of Justice has some intriguing stories to tell!
- First of the Five: This impressive structure holds the distinction of being the first building completed according to Wilder and White's Capitol Campus plan. Construction began in 1912, and it stood finished by 1920 (1).
- From Quarry to Foundation: The building exterior is made from Washington sourced rock. The sandstone hails from Wilkenson in Pierce County, while the foundation is built with granite from the small town of Baring in King County (2).
- A Constructive Working Environment?: In 1913, as soon as the walls and roof went up, The Supreme Court, Law Library, and Attorney General's office moved in. The state employees and judges went to work within the partially completed structure alongside construction workers still finishing the interior. It would be a full seven years more before construction would conclude (2)!
- An Unusual Tenant: Like many of the other buildings at the capitol, the Temple of Justice has housed various agencies over the years. One of the more unusual occupants? The Department of Highways, who reportedly used the boiler room as a "materials testing facility" for a few years in the 1920s (3)!
- A Bit Shaken but Still Standing: In 1987, the Temple of Justice underwent a significant seismic retrofit, reinforcing its structure against future earthquakes. This upgrade proved its worth during the 2001 Nisqually earthquake. The building sustained only cosmetic damage (2). However, one notable event occurred: a carved sandstone block broke off the exterior near the back entrance! Look closely at the north side of the building. Above the doors, you'll see three cartouche and garland emblems. One of these blocks is a noticeably lighter color – that's the replacement for the one that fell. For a chance to see the original, earthquake-damaged block of Wilkenson sandstone, take a short detour down the heritage trail switchbacks to Reference Point 2 (N 47° 02.285′ W 122° 54.285′).

Facts and Features of the Legislative building:
As you explore, here are some interesting details about the building:
- The Capitol's dome isn't just impressive to look at; it's the tallest masonry dome in North America, rising a remarkable 102 feet! The entire building stretches to a height of 287 feet (1). Interestingly, when it was first built, it was the fourth tallest of its kind in the world (2).
- Look up in the rotunda and you'll see a chandelier with a story of its own – it's the largest one ever created by Tiffany Co., weighing in at around 5 tons (2)! There's even a story about it mysteriously swinging one April morning, a tale you can read here (3): The Swinging Chandelier: A Story for April 1 by Ralph Munro
- The building's beauty is also in the many materials used in its construction, each with a unique origin:
- The warm-toned sandstone you see on the exterior comes from Wilkeson, WA and the durable granite came from Index, WA (4).
- The sleek marble in the main corridors was sourced from Alaska.
- The elegant marble gracing the State Reception Room was imported from Italy.
- The Senate Chamber features marble brought in from Germany.
- The House Chamber showcases marble from France (2).

About the East Capitol Campus:
Following the completion of the Capitol Complex, the state recognized a growing need for more office space as agencies expanded. Additionally, some agencies had established headquarters in cities like Seattle. A significant turning point came in 1954 with the Washington State Supreme Court case Lemon v. Langlie. The court ruled, based on Article 14 Section 1 of the State Constitution (on display in the Secretary of State's office), that Olympia was the permanent "seat of government." This decision mandated that the heads of all state agencies be located near or within Olympia. Although the exact geographic limits of the "seat of government" weren't specified (leaving areas like Tumwater and Lacey ambiguous), the need for agencies in other cities to be located in the Olympia area was clear. This undoubtedly spurred the rapid construction of new buildings on the east side of the capitol in the 1960s, following the initial east campus design in 1958.
For more detailed information about the East Capitol Campus and the interpretation of the "seat of government," you can explore these resources:

Stage 3: Washington Archives Building

Open 8:30 AM - 4:30 PM M-F
N 47° 02.220′ W 122° 54.010′
Exploring the Washington State Archives: What Awaits You?
History on Display: The archives feature rotating exhibits highlighting key events and figures from Washington's history.
A Flame from the Games: Get a close look at one of the Olympic torches carried during the 1996 Summer Olympic torch relay.
A General Letter: Examine a historic letter written by General George Washington.
Start a Research Journey: Research state documents by scheduling an appointment ahead of time via email at research@sos.wa.gov. This allows the archives staff to prepare for your visit and locate the necessary materials before you arrive.
Access from Anywhere: Many documents are also available online through the Digital Archives.
More to Discover with a Group: If you have a group of 4-5 interested people, you can email the archives ahead of time to see if a guided tour is available for a future date.
Facts and Features of the Archives:
- More than Just Archives: The State Archives building is unique in that it is constructed mostly underground (1). In fact, it is the only building at the capitol with full size trees (Littleleaf Lindens) growing on it's roof! The hidden location means that it remains unseen from Capitol Way and from above, but this low profile is more than just coincidence. Built between 1962 and 1963 in the middle of the Cold War, the building was intentionally designed with a dual purpose to also serve as a nuclear bomb shelter (2).
- What gets Archived Here? While the Archives is a repository for significant historical documents, it doesn't house all state records. Current records, like birth and death certificates handled by the State Department of Health, remain with that agency. You can find more details in the Washington State Archives FAQ.
- Preserving History for All: In line with its mission, one of the State Archivist's primary responsibilities, as outlined in RCW 40-14.020.(2), is to: “…centralize the archives of the state of Washington, to make them available for reference and scholarship, and to insure their proper preservation.” This ensures that these valuable historical records are accessible to everyone for research and learning.

Another Geological Bonus Outside! If you take a moment to look carefully in the visitor parking lot, you can observe the formation of calthemite stalactites (soda straws) (See Reference Point 3 N 47° 02.247′ W 122° 53.920′). These calcium carbonate structures form in a similar way to natural stalactites but use a different chemical reaction to obtain the same effect.
In limestone caves, stalactites naturally from when slightly acidic water dissolves the Calcium Carbonate (CaCO3) from limestone and then precipitates it out when it reacts with the air in the cavern.
In man-made structures, the rainwater seeping through cracks in the concrete, leaches out Calcium hydroxide (Ca(OH)2). When the water comes into contact with the air there is a chemical reaction that forms CaCO3 precipitate. On the ground under the soda straws, you might see a slight bump; this is the calthemite stalagmite. It is a bit fitting that these can be seen at the natural resource building. Sometimes the features are removed, but because they form using a different chemical process than natural stalactites they grow back much faster. You may start noticing these on other buildings and cement structures throughout Washington.
