Räpina Mäemõisa Manor House, also known as Sillapää Castle representing the Late Classical style was built in the middle of the 19th century. The centre and annexes of the original building had two storeys which were connected with one-storey galleries. The rear of the building is decorated by four Ionic columns with triangular pediment portico. In 1924 the predecessor of the gardening school started its activities in the building.  During 1937-1938 the castle was reconstructed as a fully two-storey building.

Today the Manor House accommodates the Räpina Local Lore and Gardening Museum, the Räpina Music School and the Räpina Folk School.
