Early Christian Basilica Of Saint Achilles

The ruins of the Early Christian Basilica of Saint Achilles lie on the Frourion Hill in Larissa, near the ancient theatre and the church of Agios Achillios, and they are among the most important Christian monuments in Thessaly. The basilica dates to the fifth or sixth century, when Larissa was one of the leading bishoprics of the region. According to tradition it was built over the tomb of Saint Achillios, the fourth-century bishop who attended the Council of Nicaea and became the patron saint of the city.

Basilicas of this type had a standard plan. A narthex, or entrance porch, led into a large hall divided into a central nave and two side aisles by rows of columns, ending in a semicircular apse at the eastern end where the altar stood. The Larissa basilica follows this pattern in outline, and what remains today are the foundations, parts of the walls and the layout of the aisles. The floor of the narthex preserves mosaics in geometric patterns, a reminder of the colour and decoration that once filled the church. Among the finds are vaulted tombs, thought to be associated with the saint or with early Christian burials, and some are decorated with painted crosses.

The site shows how a Christian city was built on top of a classical one. The same hill carried the ancient acropolis, and the stones of earlier buildings were reused in the basilica. Later centuries brought fortification and further damage, and the remains were rediscovered and excavated in modern times. Today the visible ruin is modest, but the plan is readable, and informational signs help visitors imagine the building.

Relics of Achillios were carried to the Prespa lakes in the tenth century, and a church there still bears his name, which shows the saint's importance to the Byzantine world. In Larissa, the cult is still alive, and his feast in May is marked with services and celebrations in the city.

The ruins are a short walk from the city centre, and the setting under trees is peaceful. Surfaces are uneven, and the area can be slippery after rain. A visit takes around twenty to thirty minutes, and it is best combined with the Ancient Theatre of Larissa and the church above. Hours of access can change, so check locally before you go.
