Royal Fort House and Gardens

The Royal Fort House was built in the 18th century on the site of an old fort used in the English Civil war. Three different architects influenced the building and brought three styles of building to the project. If you look you will see Baroque, Palladian and Rococo styles of architecture. The gardens were designed by Humphry Repton in around 1800.
Today the building is part of the university of Bristol, used by the faculty of science.

The Royal Fort House is a historic house in Tyndalls Park, Bristol. The building currently houses the University of Bristol's Faculty of Science offices, the Brigstow Institute, Elizabeth Blackwell Institute for Health Research, the Cabot Institute and the Jean Golding Institute for data-intensive research.

The house was built for Thomas Tyndall KCB, in the 18th century, on the site of bastions which were fought over during the English Civil War and demolished in 1655. The Baroque, Palladian and Rococo styles of architecture are because of the work of three different architects: James Bridges, Thomas Paty, John Wallis. The garden was laid out by Humphry Repton around 1800.
