The Fountain of Armés (Portuguese: Fonte de Armés), alternatively called the Fountain of the Moors (Portuguese: Fonte dos Mouros), is a 1st-century fountain built by Lucius Iulius Maelo Caudicus, an Olisipo flamen, to honour the Roman Emperor Augustus, in the village of Armés, civil parish of Terrugem in Sintra.

It is suggested that the tank and fountain were constructed in the 1st century A.D.[1] Recent analysis by Cardim Ribeiro suggests that the inscription was altered in relation to its original position, in order to facilitate access to the tank.

A V G D S F", translated as "Lucius Iulius Maelo Caudicus, flamen of the Divine Augustus, made this (monument) at his own expense".

The part of the left lateral wall is a thicker, broader and irregular slab, seemingly primitive in origin.

A subterranean conduit, which ends in a circular hole near the right edge of the posterior wall, 85 centimetres from the bottom, brings water to the tank.
