In 27 BC, Marcus Agrippa initiated the construction of the old Pantheon, Rome on his own property in the Campus Martius.  The facade is the only portion of Agrippa’s building still extant today, the original having burned in a massive fire in AD 80 (the current structure, including the famous dome, was built under Trajan and Hadrian).

The (still original) inscription on the temple’s front reads:

M·AGRIPPA·L·F·COS·TERTIVM·FECIT

or in full, “M[arcus] Agrippa L[ucii] f[ilius] co[n]s[ul] tertium fecit,” meaning “Marcus Agrippa, son of Lucius, made [this building] when consul for the third time.”
