Description
Verulamium is a significant archaeological site, recognized as the third largest city and the only municipium of Roman Britain. Local builders quarried the area until the 19th century. Much of the site has been carefully excavated and then covered again to create playing fields. Notable features include mosaic floors and other artworks displayed in the Museum. The visible remains consist of sections of the city wall, gateways, and a mosaic floor with an underlying hypocaust, which is protected by a modern building in the center of the fields.
The individual parts of masonry that are visible include:
- A fragment of wall located to the west of the city.
- A fragment of wall situated to the southwest of the city.
- A fragment of wall that includes a tower at the southern point of the city.
- A long stretch of wall that incorporates a tower and the remains of a gateway along the southern boundary of the city.
- A fragment of wall on the eastern boundary of the city.
- Part of a Roman house featuring a mosaic floor and hypocaust, also protected by a modern building.
- The corner of a building that was part of the Forum of the Roman city.
