Abbey of San Leonardo di Siponto

The Abbey of San Leonardo di Siponto is a Romanesque church in Manfredonia distinguished by its carved stone details and elaborate northern portal. The complex originally contained three main sections: the church building, the monastery, and a hospital wing that accommodated travelers, with foundations of each part still visible today.

Founded in the 12th century, the monastery grew into an important facility for pilgrims heading toward nearby sacred sites. Over the centuries its function evolved, and the complex eventually fell into decline, leaving behind the ruins visible today.

For centuries this abbey served as a stopping point for pilgrims traveling toward sacred destinations, and the layout still reflects how religious communities welcomed and cared for travelers passing through. The remains of the hospital ward show how central hospitality was to monastic life.

The site can be explored on foot, with the ruins clearly visible from outside and offering visitors a chance to trace the footprints of the original buildings. Plan time for a leisurely walk to examine all sections of the former complex.

The church contains two openings that function as gnomon holes, marking seasonal changes through patterns of sunlight during the year. These ancient markers track the sun's position at the summer solstice and spring and autumn equinoxes.
