Description
Belle Isle, also known as Island House and Longholme, was built in 1774 and designed by John Plaw. It is notable for being the first house in the Lake District constructed for picturesque reasons and features a unique circular plan. The building is topped with a dome that has a lantern. The entrance is marked by an Ionic portico supported by four unfluted columns, while Venetian windows are present on the other cardinal sides. The basement is square, and the structure consists of three storeys and attics above, all within a cylindrical form. The island was landscaped by Thomas White in the 1780s.
