Ostia AnticaMarch 11, 2017 in Italy ⋅ ☀️ 61 °F
Old roman port city that was abandoned when the Tiber river changed its course. Lots of low brick walls forming a maze of shops, baths, houses, and temples. Here are some photos that show the ruins followed by a set of photos showing the tiles in the baths.
