Last night we watched two shows, one on the first Franciscan monastery in England, and one on Mine Howe in Orkney. These led to research on

dates for Thomas a Becket
date for first Franciscan monastery
what is a howe, anyhow?

When the DH and I visit cathedrals, we are usually the only people looking at the floors, much less photographing them. Yet the floors of ancient buildings are often quite interesting. In the show on the monastery we learned a lot about medieval tile.
