Somerleyton Hall is a country house in the village of Somerleyton near Lowestoft, Suffolk, England. The hall is Grade II* listed on the National Heritage List for England, and its landscaped park and formal gardens are also Grade II* listed on the Register of Historic Parks and Gardens.
The formal gardens cover 12 acres (4.9 ha) and form part of the 5,000-acre (2,000 ha) estate (7.7 square miles). They feature a yew hedge maze, one of the finest in Britain, created by William Andrews Nesfield in 1846, and a ridge and furrow greenhouse designed by Joseph Paxton, the architect of The Crystal Palace. There is also a walled garden, an aviary, a loggia and a 90-metre (300 ft) long pergola, covered with roses and wisteria. The more informal areas of the garden feature rhododendrons and azaleas and a fine collection of specimen trees.
Several pieces of garden ornaments and statuary are listed at Somerleyton Hall; these include the statue of Atlanta, the group of four urns around the sundial, as well as the sundial, all are listed Grade II. In the formal gardens, the four urns in the centre and the four stone troughs are both listed Grade II.
The remains of the Winter Garden and the boundary walling to the formal gardens are listed Grade II. The cistern at the south of the terrace to and the retaining wall to the garden front are listed Grade II. The screen wall to entrance front of the hall is Grade II listed.
The South Lodge and the gates to Somerleyton Hall are listed Grade II.
In 1240 a manor house was built on the site of Somerleyton Hall by Sir Peter Fitzosbert, whose daughter married into the Jernegan family. The male line of the Fitzosberts ended, and the Jernegans held the estate until 1604.
The next owner was Admiral Sir Thomas Allin, a native of Lowestoft. He took part in the Battle of Lowestoft (1665) and the Battle of Solebay at Southwold in 1672. Eventually, the male line of that family also died out.
In 1843 Somerleyton Hall and Park were bought by the prosperous entrepreneur and MP Samuel Morton Peto. For the next seven years he carried out extensive rebuilding, creating an Anglo-Italian architecture masterpiece. Paintings were specially commissioned for the house, and the gardens and grounds were completely redesigned. Peto employed Prince Albert's architect John Thomas; the clock tower houses a clock designed by Benjamin Vulliamy. Peto had garden features designed by William Andrews Nesfield and Joseph Paxton. Peto's son, Harold Peto, became a noted garden-designer, but it is not known whether he was influenced by the gardens of Somerlyton.
In 1863 the Somerleyton estate was sold to Sir Francis Crossley of Halifax, West Yorkshire, a carpet manufacturer, who, like Peto, was a philanthropist and a Member of Parliament. Sir Francis' son Savile was created Baron Somerleyton in 1916.
The house is now held by Hugh Crossley, 4th Baron Somerleyton and inhabited by the family. The family motto is 'Everything that is good comes from above'. In 1998 Lord and Lady Somerleyton commissioned the English artist Jonathan Myles-Lea, a specialist in country houses, gardens and estates, to paint Somerleyton Hall.
The house and grounds were used to stand in for Sandringham House in Stephen Poliakoff's 2003 television drama The Lost Prince, and the house again in Peter Morgan's 2020 series The Crown.
The house and its grounds featured as the principal location in "Neck", the sixth episode in the first series of Tales of the Unexpected (1976), and the maze in episode 2 of the 1989 game show Interceptor.
