Though this is slightly dated now, I thought it was still very interesting. Archaeologists have reconstructed what they think Greyfriars, the place which held Richard III's remains, looked like. It was originally constructed in 1230, and was one of the first Franciscan Friaries in England. Using old glass, stone, and foundations found at the site of Richard's dig, archaeologists were able to piece together what Greyfriars looked like.
This article goes into a lot more detail, as well as provides artists' reconstructions of what Greyfriars might have looked like inside and out!
