Basilicas and baptismal buildings

The Basilica of Sant’Ambrogio preserves a Romanesque church built on an early Christian foundation. An arcaded courtyard precedes its broad façade, while ribbed vaults cover the principal nave and galleries rise above the side aisles. The brickwork, carved capitals and repeated arches define both the enclosed church and the open space before it.

The Baptistery of San Giovanni alle Fonti, beneath Milan Cathedral, preserves the excavated outline of a separate building used for baptism. Its octagonal walls surround a central baptismal basin, with alternating rectangular and curved recesses around the perimeter. These remains belong to the late Roman episcopal complex, centuries before the present Gothic cathedral was built above it.

Gothic cathedrals and royal chapels

At Cologne Cathedral in Germany, the medieval choir and its surrounding chapels preserve the eastern part of a much longer building project. Tall windows rise above the arcades, while an ambulatory connects the chapels around the sanctuary. The nave and famous western towers were completed in the nineteenth century, so their date differs from that of the medieval choir.

Sainte-Chapelle in Paris was built as a royal chapel to house Passion relics. Its lower chapel supports a much taller upper space, where stained-glass windows occupy almost the whole area between the slender structural supports. The two-storey arrangement remains the building’s central feature. The present spire and much of the restored decorative finish belong to nineteenth-century work.

Monastic churches, halls and teaching rooms

At Glendalough in Ireland, stone churches, a double-arched gateway and a round tower preserve the layout of a monastic settlement. The tower has a raised entrance and openings at successive levels; its conical cap was rebuilt using original stones. The ruined cathedral combines an earlier nave with a later choir and sacristy, allowing different phases of the settlement’s church building to be traced.

Sanahin Monastery in Armenia brings domed churches, entrance halls, a library and teaching spaces into a closely grouped stone complex. The principal churches stand only a short distance apart, with later buildings occupying the intervening spaces. Vaults, arches and carved doorways distinguish rooms used for worship, assembly and study. The buildings developed chiefly between the tenth and thirteenth centuries, with later repairs to domes and roofs.

Fortified churches and refuge enclosures

The Fortified Church of Prejmer in Romania stands inside a high circular wall. Multiple levels of rooms line the enclosure, providing storage and refuge for the surrounding community. A long defended entrance passage controlled access to the interior.

The church itself has an early Gothic cross-shaped plan and retains a late medieval painted altarpiece. Church and enclosure served connected but distinct purposes: worship occupied the central building, while the perimeter accommodated supplies and people during attacks. Restoration has maintained the unusually complete arrangement of the complex.

Royal monasteries and religious residences

The Royal Monastery of San Lorenzo de El Escorial in Spain extends across a large grid of courts and corridors. A central basilica stands between monastic and royal areas, with a library, school and burial spaces forming part of the wider foundation. Grey granite façades, regular windows and corner towers give the exterior a restrained appearance.

El Escorial was built for Philip II in the sixteenth century. Its scale and carefully divided plan preserve a religious institution designed together with the residence and burial place of a royal dynasty.
