Cadw's description

Located on rising ground in the 'Woodland Garden' to the east of Bryn Bras Castle.

The observatory was built in the 1920s during the ownership of Duncan Alves and replaced a summer house previously on the site.

Observatory. Circular tower of rather dumpy proportion. Rendered rubblestone on simple plinth with rendered brick parapet and horizontal railing to flat roof. Round-headed windows with iron bars but no glazing and entrance on south-east reached by a short flight of steps; stone corbel table below parapet.

Interior not accessible at time of Survey (February 1999) but has one ground-floor room with staircase leading to viewing platform on roof.

Included as one of a number of garden structures erected in the 1920s, an important period for the development of the gardens and grounds at Bryn Bras Castle.
