Chiesa di Santa Maria di Portonovo

The Church of Santa Maria di Portonovo is a Romanesque Benedictine church on the coast below Monte Conero, with a Greek-cross plan and an octagonal dome.

Why it matters

The church is a distinctive example of Romanesque architecture on the Adriatic coast. Its small scale, unusual plan and survival after the nearby monastery was destroyed preserve a record of Benedictine life in this isolated coastal landscape.

What to notice

Three semicircular apses project from the white Conero limestone walls. The Greek-cross plan is crowned by an octagonal dome set on a square drum. Pairs of narrow windows illuminate the interior, and the original yellow-stone and terracotta floor survives.

Context and history

The church is dated to around 1034 and was built by Benedictine monks. The adjacent monastery was sacked and largely destroyed around 1500, while the church survived. Later defensive structures in the bay include the Clementine watchtower of 1716 and a Napoleonic fort built in 1808. Restoration in the late twentieth century returned the church to use.
