The Design of Convent Castles
The convent castle of the Teutonic Order was one of the most sophisticated building types of medieval Europe, and the design of the convent castle was, in its mature form, an architectural solution to a particularly demanding set of institutional requirements. The convent castle had to house a monastic community, defend the surrounding territory, and function as a regional centre of administration — all at the same time, and all in a single building. The architectural response was the concentric plan, in which the claustral plan of the monastic tradition was enclosed within a defensive perimeter.
The Concentric Plan
The defining feature of the convent castle was the concentric plan, in which the buildings were arranged in two or three nested enclosures. The innermost enclosure, the cloister garth, was reserved for the principal conventual buildings. The middle enclosure was reserved for the administration. The outer enclosure, the Vorburg, was reserved for the garrison, the stables, the smithy, and the workshops. The arrangement was, in essence, a monastic cloister inserted into a concentric castle, and the result was a building type in which the monastic and the military elements were, for the first time, fully reconciled.
The concentric plan of the convent castle was not, in any narrow sense, an invention of the Order. The basic idea of a series of nested defensive enclosures was inherited from the secular castle-building tradition, and the basic idea of a monastic cloister was inherited from the Cistercian and Premonstratensian traditions. The originality of the Order’s contribution lay in the combination of the two ideas.
The Inner Enclosure
The four principal conventual buildings were arranged around the cloister garth in a manner that closely followed the canonical claustral plan. The chapel was placed on the north side of the inner enclosure, and was a substantial hall church with a long nave, two aisles, a polygonal apse, and a tower over the crossing. The chapel was the largest single space in the convent, and the most impressive surviving example is the chapel of the High Castle of Marienburg, one of the largest medieval chapel interiors in Europe.
The refectory, in German Remter, was placed on the south side of the inner enclosure, and was a long rectangular hall, typically divided by columns or piers into a nave and two aisles, and roofed with a ribbed vault. The refectory was the principal communal space of the convent, and is treated in detail in the article on the refectory and chapter house.
The chapter house, in German Kapitelhaus, was placed on the east side of the inner enclosure, and was a smaller rectangular hall, usually with a ribbed vault, in which the daily chapter meeting of the convent was held. The dormitory was placed on the upper floor of the east range, above the chapter house, and was a single undivided hall in which the brethren slept in curtained cubicles.
The Middle Enclosure
The middle enclosure, where it existed, was reserved for the administrative and service functions of the Komturei. The principal building was the Komtur’s lodging, a substantial residential block on the west side of the inner enclosure. In the larger convent castles, the Komtur’s lodging was a building of considerable architectural pretension, with a separate entrance and a separate staircase. The most impressive example is the Grand Master’s palace in the High Castle of Marienburg, a building of three storeys with a long gallery, a great hall, and a private chapel.
The other principal buildings of the middle enclosure were the chancery, the treasury, the armoury, the brewery, the bakery, and the infirmary. The arrangement of these buildings varied from castle to castle, and there was no canonical pattern.
The Outer Enclosure
The outer enclosure, the Vorburg, was reserved for the garrison, the stables, the smithy, the mills, and the craftsmen’s workshops. The Vorburg was a substantial fortified courtyard, often larger than the cloister garth itself, and was surrounded by a curtain wall pierced by a single main gatehouse. The most impressive example is the gatehouse of the Marienburg, one of the largest medieval gatehouses in Europe.
The outer enclosure was, in effect, the working courtyard of the Komturei. The stables accommodated the substantial body of horses maintained for the mounted brethren and the garrison. The smithy was the place in which weapons, armour, and ironwork were manufactured and repaired. The mills — typically two, one for grain and one for fulling — were essential to the economic self-sufficiency of the Komturei.
The Defensive Perimeter
The whole complex was surrounded by a defensive perimeter, the Zwinger, consisting of an inner curtain wall, a moat, and an outer curtain wall. The inner curtain wall was a substantial brick wall, typically ten to fifteen metres high, with a wall-walk and a parapet. The moat was, in the Prussian castles, typically a wet moat, fed by a diverted stream, and was crossed by a bridge in front of the main gatehouse. The outer curtain wall was a lower wall, designed to delay an assault and to provide a covered way for the defenders. The defensive perimeter is examined in detail in the article on defensive walls and moats, and the brick construction of the perimeter is treated in the article on brick Gothic architecture.
