St Catherine's Court is a manor house in a secluded valley north of Bath, Somerset, England. It is a Grade I listed property. The gardens are Grade II* listed on the Register of Historic Parks and Gardens of special historic interest in England.The original house was a priory grange for the monks of Bath Abbey adjacent to the Church of St Catherine. At the Dissolution of the Monasteries, the manor was granted to John Malte and passed down to the courtier John Harington. It was bought in 1591 by John Blanchard and housed his descendants for generations, but the property fell into disrepair. In the 19th century, the house was bought by Colonel Joseph Holden Strutt who renovated it, with the work being continued by his sons. In 1984, actress Jane Seymour bought the house and carried out further renovation. During her ownership, the property was used as a recording studio and party venue, which caused complaints among the neighbours. It has since been further extended and is now rented out as a wedding venue.
The fabric of the building has changed over the centuries with a two-storey porch being added in 1610. Further extensions were added in the early 19th century, and the orangery and library were added in the early 20th century. In the 21st century, another addition including a swimming pool was added. The house is surrounded by 4 hectares (9.9 acres) of landscaped grounds with terraces joined by flights of steps. The barn within the grounds is from the 13th to 15th centuries.
