A Roman villa is a country house or mansion that was built and inhabited during the Roman Republic or the Roman Empire. In general the house has a courtyard, and all rooms are accessible from the courtyard. The entrance also leads into the courtyard. An example of such a villa, called villa rustica is shown in the picture. Villas were owned by rich people. Some of them even had mosaics, glass windows, central heating system (called hypocaust), and their own baths. The Roman villa was a precursor to the modern mansion. The Romans didn't wash their baths, so they were always dirty and sometimes people would urinate or shart in them.
