[1] In the late third century, to defend against attack from barbarians a town wall was built with seven gates.

[2][3] The pavement was discovered after World War II bombing on 1 June 1942, and excavations were carried out by Audrey Williams and Sheppard Frere between 1945 and 1946.

This is the best local example of a Roman townhouse; they found that this masonry building had undergone many alterations over a long period, adding several rooms, corridors and mosaics before abandonment in the 5th century.

Parts of one of the largest theatres in Britain had been located beneath nearby streets and buildings.

Substantial elements of public baths have been excavated underneath modern buildings in St Margaret's Street.

[4][11] The scheduled monument listing describes the pavement thus: "The excavations of 1945−1946 uncovered a series of three mosaic panels which decorate the remains of a corridor of a Roman house".

[11] There is a lot of Roman glass including some decorated examples, silver spoons, an axe, tweezers, a plumb weight and dice.

A computer screen demonstrates the possible appearance of the house in Roman Britain, with images of the pavement being excavated.

[4][13][14] An interactive screen enables visitors to tour the Temple site of Roman Canterbury.

Before leaving, the visitor can handle actual Roman artefacts, alongside a guide to identifying the objects.

The "Make your own magnetic mosaics" and "Dress like a Roman" activities are intended to entertain and educate all ages.

(3) The Butchery Lane Roman building was first excavated in 1945–6 by Audrey Williams and Sheppard Frere.

A hoard of 50 third century cordiate coins was found in the area west of the hypocaust stokehole in the Roman building in Butchery Lane.
