Most is made up of eight city parts and villages: Most, Stary Most, Cepirohy, Komorany, Rudolice, Sous, Velebudice and Vtelno.

Rudolice is home to the Chanov housing estate, created during the communist era, which has become a symbol of the poverty and ghettoization of many Romani people in the Czech Republic.

Vtelno used to be a village near Most. When the new city was built near it, Vtelno became an integral part of Most. It has a church, a historical Baroque manor, and many monoliths and sculptures that have been collected during the era of demolition of villages in the region (due to coal mining).

As a redeveloped city, Most does not have many historical sights, yet there are two important ones: Hnevin Castle and the Gothic Church of the Assumption of the Virgin Mary. On the other hand, there are many amusement facilities which can be visited: planetarium, observatory, autodrome, aquadrome or hippodrome.
