The brick tower or belvedere on Nunhide Hill was built in 1769 by Reverend Henry Wilder (1744–1814) while he was courting Joan Thoyts (c. 1748–1837), younger sister of John Thoyts of Sulhamstead House.

[1] Wilder constructed the tower so that it could be seen from Thoyts' home as well as from his own residence, Sulham House.

The painted first floor room was accessed by an exterior wooden staircase.

[1] The two floors above ground level featured glazed ogive windows.

[1] In the late 19th century the building's windows were bricked up and the tower became a dovecote.
