Chiesa millenaria, Romanesque church in Ruta, Camogli, Italy

Chiesa millenaria is a 13th-century Romanesque church in Ruta, a hamlet of Camogli, with a single apse-ended nave and exposed stone walls. It stands on a grassy slope of Monte Esoli, surrounded by trees, and is also known locally as Chiesa Vecchia.

The church dates from the 13th century and was the only church in Ruta until 1627, when it was replaced as parish church by the church of San Michele Arcangelo further down the road to Bana. Originally dedicated to Saint Michael the Archangel, it is now dedicated to the Sacred Heart of Jesus. It was abandoned after a fire set by Napoleon's French troops under General Andrea Massena in the late 18th century.

The church carries visible marks of changing devotions across the centuries, with its walls reflecting the spiritual needs of the community through different eras. People continue to gather here for local celebrations and religious observances that shape village life.

The church can be reached via Via XXV Aprile in Ruta, where a path continues toward Monte Esoli and the Madonna di Caravaggio sanctuary. The walk involves a moderate climb, so sturdy footwear and steady pacing are advisable.

In the early 1900s, the building underwent major reconstruction that included adding a sacristy and removing the original floor with its historical tomb slabs. This renovation significantly altered the interior structure and replaced elements that had survived for centuries.
