Complesso di San Pietro in Consavia e Museo Archeologico

At the head of Corso Vittorio Alfieri, the Complesso di San Pietro in Consavia gathers a circular Romanesque rotunda built to recall the Holy Sepulchre, a richly terracotta-decorated Gothic chapel, a 15th-century cloister and the rooms of a Knights' priory that once also housed Asti's archaeological museum, bringing together nearly nine centuries of the city's history.

Why it matters

San Pietro in Consavia is one of the most important Romanesque monuments in Asti, and its story is unusual. The Rotonda was built between 1100 and 1130 as a deliberate architectural echo of the Holy Sepulchre in Jerusalem: a round church with a tall dome and an ambulatory, dedicated to the Sepulchre itself. In 1120 the site became the priory of the Cavalieri Gerosolimitani — the Knights of the Holy Sepulchre, later Hospitallers — who made it their seat for almost seven centuries, until 1798. When the Knights formally settled in 1169, the original dedication shifted to "San Pietro in Consavia", the name by which the complex is known. The priory linked Asti with the traditions of the Jerusalem pilgrimage.

What to notice

The Rotonda is the heart of the complex. Its circular plan is ringed by an ambulatory, and eight columns of alternating terracotta and tuff, capped with cubic capitals, carry a pavilion vault frescoed in the 17th century. The interplay of brick and pale stone in the columns is the recurring visual note throughout the complex.

The Cappella Valperga, built between 1446 and 1467 at the request of the prior Giorgio Valperga, is a square chapel whose fame rests on its exterior: terracotta decoration of remarkable quality, with fifteen sculpted panels running along the cornice of the central window and carved mascarons — grotesque face-corbels — supporting the vault ribs. It is one of the finest pieces of 15th-century terracotta ornament in the region.

The Chiostro took its present Quattrocento form in the 15th century, its round pillars and groin vaults enclosing a quiet court. Much of the surrounding prioral house was rebuilt during the 1930–31 restoration of the whole complex; one part of it had served pilgrims as a hospital, a reminder of the priory's original function on the Jerusalem route. From 1741 the Rotonda also served as Asti's baptistery — the only period in which the building, often called the Battistero di San Pietro, actually performed that role.

Context and history

The complex brings together several historical phases. The Rotonda (1100–1130) expresses the Jerusalem devotions of the early 12th century; the Knights' arrival in 1169 institutionalised them; the Valperga Chapel (1446–1467) shows the priory at its Renaissance height; the cloister crystallised in the same century; and the 1741 baptistery conversion reflects an 18th-century need to give Asti a grand baptismal church. Suppressed with the Knights in 1798, the buildings later decayed. A restoration campaign in 1930–31 conserved the complex, and the Archaeological Museum of Asti was installed in the priory rooms with the city's Roman and early medieval finds. The Rotonda later also hosted the paleontological collection before those fossils moved to Palazzo Michelerio. The complex brings together Asti's medieval architecture and archaeological collections.
