Historical octagonal temple near Castle Semple. A real architectural marvel for its time, despite its deterioration over the years. Built during the early-mid 1800's, the Temple (as locally known) is part of the old Lord Semple estate. Speculated uses include a "folly" to draw the attention of visitors to the mansion house, a summer house, and/or viewing platform. 

The building became deteriorated during the decline of the Castle Semple House and breakup of the estate. Can be accessed on foot via a kissing gate along Clyde Muirshiel's Semple Trail from the Sustrans cycle track between Lochwinnoch and Kilbarchan.
