Only discovered underneath Guildhall Yard in the 1980s, remains of London’s Roman-era amphitheatre can today be seen in the basement of the Guildhall Art Gallery.

Built around 70 AD initially as a simple wooden structure and then remodelled shortly after 120 AD with masonry foundations and walls and timber stands, the amphitheatre would have held as many as 7,000 spectators and was probably used for events such as public executions and other public entertainments including animal fighting and gladitorial combat.

The amphitheatre – the size of which is marked in a black line on the yard above (see picture right) – was abandoned by the mid 4th century.

Don’t expect too much – these days only remnants of the walls remain at what was ground level in the Roman era but they and the accompanying digital reconstruction give a reasonable indication of what it may have once been like.

The Museum of London runs tours of the amphitheatre with the next scheduled for 25th January, 2011. Click here for more details.
