The Triangular Lodge in Northamptonshire

The Triangular Lodge is a folly, designed and constructed between 1593 and 1597 by Sir Thomas Tresham near Rushton, Northamptonshire, England. It is now in the care of English Heritage. The stone used for the construction was alternating bands of dark and light limestone. A folly is a building constructed primarily for decoration. In the original use of the word, these buildings had no other use, but from the 19th-20th centuries the term was also applied to highly decorative buildings which had secondary practical functions such as housing, sheltering or business usage.
