Park Square, London

It consists of two facing rows of large, very classically formed, stuccoed, terraced houses with decorative lower floor balconies and a colonnade of consecutive porticos by architect John Nash, and was built in 1823–24.

[2] On the east side of the square was Britain's first and longest-lasting of four national exhibitions of the Diorama, the building of which remains, in other use – it opened from 1823 until 1852.

North-east beyond much smaller St Andrews Place, about twice the Diorama's size, was London Colosseum, built for the largest painting ever made and which was demolished in 1874 – both had large foyers and attracted many visitors.

[4] The busy road was considered dangerous, especially to children who were often taken to the park by a nursemaid, leading to the wealthy to-be residents petitioning for its building.

[7] The four corner houses project slightly, and co-front shorter terraces yet their design is highly similar by Nash, and of the same date.
