Rebels, Radicals and Rough Justice: Historic Clerkenwell
Have a look at the small Jerusalem Tavern on your right, and then keep walking.
This building dates from the early 1700s, although it only opened as a pub in the 1990s. After the pub, there's an adjacent row of Georgian terrace houses. The 1709 London Building Act stated that windows of London houses should be recessed by at least 4 inches, to hinder the spread of fire. Some of these houses do have recessed windows, so you can tell they were built after 1709.
The property in this area reaches astronomical prices that may surprise you, as this is by no means a posh area. However its convenience for City workers and its historical interest make it almost as popular as Mayfair or Belgravia.
