The Old Session House, Clerkenwell Green, London

Built in 1780 in the classical style by Middlesex County surveyor, Thomas Rogers.

The Session House was the administrative centre for the County of Middlesex until 1899 when London County Council was created. Middlesex stuggled on as a county until 1965 in different forms, when it was engulfed by London.

The building was also the biggest court in England until 1921, after which it was the HQ of W&T Avery, the weighing scales manufacturers; and then it was the London Masonic Centre.

In 2013, it was bought by Home House, a private members club for Techies, based in Portman Square, as another club for their members.

It was in the square outside of this building, called Clerkenwell Green, that the Artful Dodger started to teach Oliver how to pickpocket. About page 150 of Great Expectations if you want to read it.
