Question

Citadel had small building and houses of the common people

Answer 1

Answer:

A citadel is the core fortified area of a town or city. It may be a castle, fortress, or fortified center. The term is a diminutive of "city", meaning "little city", because it is a smaller part of the city of which it is the defensive core. Ancient Sparta had a citadel, as did many other Greek cities and towns.
