Why it's Wildland
6.4Beneath a mosaic floor in a Roman townhouse, hot air once circulated through channels cut below the room. Excavated in the 1930s, the 1,800-year-old heating system and mosaic remain in their original setting.
A compact, distinctive encounter with Roman domestic engineering: the mosaic still lies above the heating system it was made to cover. It is best understood as a focused historical stop, rather than a full-day destination on its own.

The experience
See the mosaic in its original Roman location, then look closely at the channels of the hypocaust beneath it. The small site makes a concise visit; Verulamium Museum is a worthwhile sourced extension nearby.
Things to do
Read the mosaic in its original setting
Look at the tesserae forming the floor and consider how the mosaic covered the hypocaust system below.
10–20 minutes
Trace the Roman heating system
Look for the channels beneath the floor. St Albans Museums explains that hot air circulated below floors and through walls; at this site, trenches beneath the floor carried the heat.

Verified history
The mosaic and hypocaust belonged to a large Verulamium townhouse built around AD 200, near Watling Street. The room is thought to have served as part of the house’s reception and meeting rooms. Sir Mortimer and Tessa Wheeler uncovered the remains during excavations in Verulamium Park in the 1930s. They were left in their original location rather than moved. The surviving section formed part of a suite that originally extended almost twice the length of the room preserved today.
Hidden details
The floor is part of the heating system’s story — The mosaic was laid over the hypocaust. Look for the trenches beneath the floor that allowed hot air to pass through; this system differs from the arrangement of brick supports used in some hypocausts.
The surviving room is only part of a larger suite — The preserved section was part of a suite that extended almost twice the length of the surviving room, according to Enjoy St Albans.
