The Society was founded in the 1660s, and has moved a number of times in its long history. In 1710 it moved to Crane Court in the Strand, by the 1780s it was at Somerset House, and in 1857 it moved to Burlington House in Piccadilly. In fact, it wasn't until 1967 that it moved to its current location.
