From Wikipedia:
In commemoration of the Battle of Actium (31 BC), Agrippa built and dedicated the original Pantheon during his third consulship (27 BC). Agrippa's Pantheon was destroyed along with other buildings in a huge fire in 80 AD. The current building dates from about 125 AD, during the reign of the Emperor Hadrian, as date-stamps on the bricks reveal.
