Structural Principles of Romanesque Architecture

Evolution of Romanesque Architecture

The monastery is not built in the city but in the midst of agricultural possessions. However, the 11th century shows a beginning of the revival of urban life, and in keeping with the cathedral, it became the symbol of the city. Abbots and bishops strive to realize their authority through monuments of Romanesque Architecture. This designation applies to this style because building forms are similar to the Roman world; it is a vaulted architecture where the barrel vault and the groin vault predominate, and the external austerity was already distinguished by Rome. It possesses its own variety of shapes and plans.

Key Characteristics of Romanesque Construction

The stone used is limestone, granite, or slate. Irregularly cut stone forms the earliest buildings, known as cantería. In these, they achieve an irregular but secure masonry bond. It is an architecture where marble or brick is occasionally used. Building elements include the round arch, the barrel vault, and the groin vault.

Floor Plans and Layouts

Floor plans do not follow a single design but adapt to the needs of the building. Among these, the basilica and primarily Latin cross plans stand out. These plans adapt through the multiplication of apses. The naves and pilgrimage churches use a Latin cross plan, but a triforium is added to the side naves. They also add a corridor behind the altar called an ambulatory, which includes small chapels called absidioles. The resulting layout is called a pilgrimage plan.

Structural Support and Load-Bearing Elements

The usual load-bearing pillar is the compound or cruciform pillar. It originated from the need to hold four arches: two transverse ribs and two longitudinal arches; therefore, it is used in buildings with three naves, whether they are basilical or Latin cross in design.

Vaulting and Deck Systems

The deck system is vaulted. The deck is used on transverse ribs; the barrel vault is the most advanced type used. Eventually, the barrel vault is replaced because the main nave and the aisles are covered with groin vaults that allow for better weight equilibration on the walls.

The Buttressing System

Every domed cover system needs a buttressing system to handle the pressures generated by the vault. Thick walls are constructed with holders called buttresses that directly reinforce the wall in places where the arches support the dome.

Exterior Features and Aesthetics

The exteriors clearly reflect the interior layout. The central naves always stand above the side naves. The transept of a Latin cross plan also has a similar or greater height than the central nave. The crossings are equally impressive from the outside through a tower that covers them, called a cimborrio.

Decorative and Functional Elements

Characteristic elements of Romanesque exteriors include bell towers, buttresses that match the interior arches, eaves, and projections sustained by corbels (modillones). Other features include archivolts and the tympanum, buttresses framing the interior layout, and decorated mullion jambs, along with ornamental motifs such as Lombard bands. Cloisters are square constructions that usually define monastic wings.
