Belsize Square Synagogue

Belsize House was a historic residence in Belsize Park in what is today the London Borough of Camden. It was a country estate located south of Hampstead, which was then some distance away from the outskirts of the capital. An Elizabethan manor house stood on the site. Daniel O'Neill, an Irish Cavalier in the English Civil Wars, was granted Belsize House by Charles II following the Restoration in 1660. O'Neill rebuilt the house in 1663 and it again underwent significant further remodelling from 1744 to 1746. After 1720 it became a place of public entertainment to cater to the growing traffic heading towards the fashionable Hampstead Wells. This included serving refreshments as well as turning the grounds into pleasure gardens. It soon gained a reputation for hosting gambling as well. It subsequently reverted to being a residence. The politician Spencer Perceval rented the house between 1798 and 1807. He later served as Prime Minister before his assassination in 1812. It was demolished in 1853 and replaced by a series of streets of white stucco residences to provide upmarket housing for the expanding population of the city. These included Belsize Park Gardens while Belsize Lane a little to the north is an older road. The old house stood close to what is now St Peter's Church on Belsize Square and faced eastwards. What was once the old elm-lined approach to the house is now Belsize Avenue which heads east to Haverstock Hill.

Belsize Lane is a street in the Belsize Park area of Hampstead in London. Located in the London Borough of Camden, it runs east to west from Haverstock Hill to Fitzjohns Avenue. While residential for much of the route, it also features a group of commercial properties that form the centre of Belsize Village. The Tavistock Clinic is located at its western end. It is one of the oldest roads in the area, dating back to the period when the area was largely rural and dominated by the Belsize House estate. The route is significantly older than streets immediately to its south such as Belsize Park Gardens, Belsize Avenue and Belsize Square which were only laid out after Belsize House was pulled down and redeveloped in 1853. The Belsize Tunnel, constructed by the Midland Railway in the 1860s, passes underneath the street. Near the eastern end of the street is Hunter's Lodge, a white stucco cottage designed by Joseph Parkinson in 1810 which is now Grade II listed. Closer to the western end numbers 79–93, a terrace of mid-nineteenth century stucco houses, are also listed. Number 34 is a single storey studio house built in 1975-6 which the architect Georgie Wolton designed for herself and her family, it was listed in October 2023.Outside the Tavistock Clinic is a Statue of Sigmund Freud by Oscar Nemon.

Located in the London Borough of Camden, it runs eastward from Swiss Cottage tube station to a junction with England's Lane and Belsize Park Gardens by The Washington pub. Built in the late Victorian era by William Willett it features redbrick houses with terracotta and shaped gables, in contrast to the earlier white stucco Italianate style that dominates in the streets slightly to the north on the old Belsize House estate. Construction started around 1886. The street was laid out on the former Eton College estate, after which it takes it name. The western end is pedestrianised outside Hampstead Theatre and hosts the Swiss Cottage Market. The nearby Embassy Theatre uses the site of the former Hampstead Conservatoire.

The Italianate stucco style resembled similar new neighbourhoods in Kensington. From 1855 the property developer Daniel Tidey directed the development of the street, described by Pevsner as "the most impressive stretch" notable for its paired palazzi with ionic porches. It is built on the land of the former Belsize House estate from which it takes its name, along with various other streets in the vicinity.
