This geocache is part of the Ye Olde Survey Monument Series.  I tried to find out some local history for this one however not much was forthcoming !  The actual monument itself is within a fenced off area but you can clearly see it from the co-ordinates. The official TP number is TP6393

Please take note of the Parking co-ordinates in the waypoints as this is a very busy road and there is no parking places nearby. Parking spot closes at 7pm.


At the given co-ordinates there is a notice board read this and decipher the following to find out where the cache is hidden.  Behind this board to the right you can see the YOSM.

C = Act of Parliament on 2? June 1899

In the 17th century a brick-making industry was developed near the junction of Old Redding and Common Road and run by the Bodimeade family until the end ofthe 18th century when Mary Ann Bodimeade married a Charles Blackwell.  During the 19th century the Blackwells became a large and wealthy family owning several extensive properties, including The Kiln; The Hall, Brookshill; The Cedars, Uxbridge Road; Oxhey Hall and a Manor House in Chipperfield, Hertfordshire.

In 1829 Thomas Blackwell formed a business venture with Edmund Crosse which became known as the firm of Crosse and Blackwell.  During the 19th century a number of cottages were built to house the kiln labourers and this group of dwellings near the "Case is Altered" became known as "The City", 

Ye Ole Survey Monument (YOSM) is a captivating series of caches that pays homage to the remarkable legacy of OutForTheHunt's YSM series (GC45CC).

YOSM caches are strategically positioned at or near Trig Points. These triangulation stations have played a pivotal role as surveying landmarks, contributing to the mapping of expansive territories. Some of these points, bearing historical significance, might now be situated on private land or have vanished with time. As a result, the caches are artfully placed in close proximity, reverently acknowledging the historical importance of these survey monuments.

More information, bookmarks and statistics can be found at the YOSM Website

If anybody would like to expand the Ye Ole Survey Monuments Series, please do. I would ask that you request a number for your cache first at so we can keep track of the numbers and names to avoid duplication.
