Founded by the Romans in AD 75 as Venta Silurum, this was a fortified market town for the defeated Silures tribe.
The walls are easily the most impressive town defence to survive from Roman Britain.
Here you can see short clips depicting:
The Court Yard House with its pillars that originally supported the floors and under floor heating.
The Basilica which would have been the main council chamber.
The Forum which would have hosted the market stalls
The Temple for worship
The long South city wall with City gate
Castle mound which supported originally a wooden construction and around 300AD was rebuilt in stone.
