The Cathedral of the Blessed Virgin Mary, Truro, was built in the Gothic Revival architectural style fashionable during the period, and is one of only three cathedrals in the United Kingdom with three spires. The See (or Diocese) of Truro was established in 1876 and the first bishop, Edward White Benson, was consecrated in 1877: this was the first cathedral to be built on a new site in England since Salisbury Cathedral in 1220.
Construction began in 1880 on the site of the 16th century parish church (St Mary the Virgin). Two foundation stones were laid in 1880 and the first section of the cathedral was consecrated in 1887. The central tower was completed by 1905 and the building was completed with the opening of the two western towers in 1910. The central tower and spire stands 250 feet (76 m) tall, while the western towers reach to 200 feet (61 m). An original aisle of St Mary's Church is still contained within the south-east corner of the cathedral and still functions as the city centre's parish church. Truro has a further unusual feature – a slight bend in its plan: because the cathedral is situated in the heart of the city there was little room with houses and shops packed closely about on all sides. In order to accommodate the cathedral it was necessary to bend the building six feet northward.

The cache is not at the above coordinates, but is within sight of the cathedral spires and less than a quarter of a mile away. To find the cache first take a tour of the cathedral to find the value of the letters in the following equation ;

N50 AD.(F-G)E(C-A) W005 (B-H-J)(J-A).(I+F+G+J)÷2

At the west end of the South Aisle, near the entrance you will find the large Boer War Memorial. Nearby the RNLI flag remembers the lives lost when the Solomon Browne lifeboat was lost with all hands in 1981. Between these two memorials on the west wall you will find a year below an image of King Edward VII.
A = the first number divided by the third number.

All the nave pillars, except one, are made from cream-coloured Bath stone. Find the exception - a grey coloured granite pillar which was one of two foundation stones laid in 1880.
B = the day of May this stone was placed.

To the right of the foundation stone is the baptistry, which contains the cathedral font. The wonderful red stone is Breccia marble from North Africa, the green stone is Serpentine rock from The Lizard in Cornwall.
C = the amount of Serpentine columns holding up the font.

On the floor of the chapel next to the Baptistry is a brasswork of Edward White Benson, first Bishop of Truro.
D = the total number of stars over the two angels' heads.

At the southeast corner of the Cathedral is a church within a church. The Parish Church of St Mary's has been on this spot since at least 1259 and has been incorporated into the side of the Cathedral. The Dean of the Cathedral is also the Rector of the Parish Church. Find a list of all Rectors displayed on the wall of the church. What year did William Tombs become Rector?
E = the fourth number minus the third number.

The area behind the High Altar is known as the retroquire (literally behind the Quire). Here you will find a new altar, constructed from fumed chestnut. On the column to the left of this altar is a reading from St Marks Gospel.
F = the number of the quoted chapter of St Marks.

Enter the Quire from the north side. On the south side you will find the heavily carved Bishops Chair, which in Latin is called a 'cathedra' - it is this chair that makes a church a cathedral.
The Quire stalls are made of Burmese teak with rows of carved figures of Celtic Saints below the canopies.
G = how many Celtic Saints stand on the north side of the Quire (it turns out theres an extra saint hiding behind the barrier rope, if you spot him, don't count him!).

Back in the north aisle is George Tinworth's large terracotta frieze 'The Way of the Cross', showing the procession to Calvary.
H = the number of men wearing helmets.

Moving along the north aisle you will see the painting Cornubia - The Land of the Saints. The Celtic crosses on the painting represent the parish churches of Cornwall and a key will help you identify the name of each church.
I = how many churches on Cornubia.

Behind you is the splendid brass eagle lecturn, where the bible is read every Sunday.
J = how many Evangelists support the eagle as it slays the dragon in it's talons.
