Historic house in Cumbria, England

Sizergh Castle is a stately home with garden and estate at Helsington in Cumbria, England, about 4 mile (6 km) south of Kendal. Located in historic Westmorland, the castle is a Grade I listed building. While remaining the home of the Hornyold Strickland family, the castle with its garden and estate is in the care of the National Trust. In 2016 the Sizergh estate was included in the newly extended Lake District National Park.

The Deincourt family owned this land from the 1170s. On the marriage of Elizabeth Deincourt to Sir William de Stirkeland in 1239, the estate passed into the hands of what became the Strickland family, who owned it until it was gifted to the National Trust in 1950 by Lt. Cdr. Thomas Hornyold Strickland, 7th Count della Catena, a grandson of Gerald Strickland, 1st Baron Strickland. Catherine Parr, the sixth wife of Henry VIII and a relative of the Stricklands, is thought to have lived here after her first husband died in 1533. Catherine's second husband, Lord Latymer, was kin to the dowager Lady Strickland. It was extended in Elizabethan times. Sir Thomas Strickland went into exile with James II. Around 1770, the great hall was again expanded in the Georgian style.

The gardens are registered Grade II. There is a lake, a kitchen garden and a rock garden. The rock garden, constructed in the 1920s, is the largest limestone rock garden belonging to the National Trust. Sizergh houses part of the National Collection of ferns, which are to be seen in the rock garden, the stumpery and the orchard.

In 1336 a grant from Edward III allowed Sir Walter Strickland to enclose the land around Sizergh as his exclusive park. The estate covers .

There are various types of habitat on the estate. For example, in 2014 it was reported that 35 ha of wetland habitat was being created in the Lyth Valley on the western edge of the estate. The project received funding from Natural England as part of a higher level stewardship scheme. It is hoped to attract bittern and other wildlife. Sizergh has received support from the Morecambe Bay Nature Improvement Area which was launched in 2012. It received three years of government grant funding (2012–15). Projects continue under the auspices of the Morecambe Bay Partnership, a registered charity.

Fritillary butterflies (including pearl bordered and high brown fritillary) live on the estate. It has been suggested that a group of stones on the fell form the remains of a stone circle.

The castle was featured in the ITV documentary Inside the National Trust. The room known as the Inlaid Chamber is the subject of Letitia Elizabeth Landon's poetical illustration The Queen’s Room, Sizergh Hall, Westmorland to an engraving of a painting by Thomas Allom, published in Fisher's Drawing Room Scrap Book, 1836.
