Guildhall is one of the buildings that I visited during Open House London; it wasn’t originally on my itinerary but when I found myself in the area I decided to have a look around and was very glad I did because it was definitely one of the highlights of the weekend. It’s a Grade I listed building that was built between 1411 and 1440 and is the ceremonial and administrative centre of the City of London and its corporation.
