Supreme Court, Parliament Square SW1

One of the amazing things about the former Middlesex Guildhall is that it is stone faced on all four facades, even though two of them look over narrow Little Sanctuary where most clients would have imposed a bit of economy and gone for brick or encaustic tile. But the minor facades of Middlesex Guildhall even have sculptural ornament, an unbelievable excess.
The keystones of the windows on the north side of the building show the kind of people who thronged medieval Westminster: a monk with a book, a scrivener with a scroll, an armourer with a knight's helmet and a goldsmith displaying a goblet.
