Probably the name Monteroni comes from the Latin Mons Tyronum, meaning "mount of the spear-men" and hinting at its origin as a training camp for the Roman legions.

In fact, originally the Romans apparently established a military stronghold on the hill nowadays called San Filii.

The Montoroni built the first Baronial Palace in the town in the original shape of a small fortress.

When the fief passed onto the Duke of Spongano, the Baronial Palace was enlarged and gained the current Leccese Baroque style.

Monteroni di Lecce owes the baroque period also its bell tower and the two chapels, which were in the central square (currently “Piazza I. Falconieri”) on the site currently occupied by the major church “Chiesa Matrice”.
