There has been a settlement at Chester, since the Romans built a fort here in AD79. The city walls are the most complete city walls in Britain, with some sections still intact from 120 AD, while most of the existing wall is Medieval. Within the walls the red sandstone Cathedral dates from 1093 and stands it is believed on the same site as a temple dedicated to Apollo existed until Christianity became the religion of the Roman Empire. Also within the walls The Rows are a series of half-timbered buildings joined with long galleries which make a shopping mall – Tudor style!
