What is a insula in ancient rome?

Answer 1

It was an apartment block. It housed the middle and lower classes. Their quality was often poor due to speculation. They were built cheaply, originally in timber and mud brick, letter in low quality concrete. They could be up to 6-7 floors high. They had shops on the ground floor. The larger and more expensive flats were on the lower floors and the smaller flats were on the higher floors. The former had water and sanitation. The latter were cheaper and less safe in case of fire. They had no water, toilets or heating. They were overcrowded and were used only for sleeping. The poorer people eat and spent most of the time outdoors. Most Romans used outdoors public toilets.

The large single-family houses of the rich were called domus.
