Sagrada Familia part 3/3 - Interior


The church plan is that of a Latin cross with five aisles. The central nave vaults reach forty-five metres (150 ft) while the side nave vaults reach thirty metres (100 ft). The transept has three aisles. The columns are on a 7.5 metre (25 ft) grid. However, the columns of the apse, resting on del Villar's foundation, do not adhere to the grid, requiring a section of columns of the ambulatory to transition to the grid thus creating a horseshoe pattern to the layout of those columns. The crossing rests on the four central columns of porphyry supporting a great hyperboloid surrounded by two rings of twelve hyperboloids (currently under construction). The central vault reaches sixty metres (200 ft). The apse is capped by a hyperboloid vault reaching seventy-five metres (250 ft). Gaudí intended that a visitor standing at the main entrance be able to see the vaults of the nave, crossing, and apse; thus the graduated increase in vault loft

There are gaps in the floor of the apse, providing a view down into the crypt below.
The columns of the interior are a unique Gaudí design. Besides branching to support their load, their ever-changing surfaces are the result of the intersection of various geometric forms. The simplest example is that of a square base evolving into an octagon as the column rises, then a sixteen-sided form, and eventually to a circle. This effect is the result of a three-dimensional intersection of helicoidal columns (for example a square cross-section column twisting clockwise and a similar one twisting counter-clockwise).
Essentially none of the interior surfaces are flat; the ornamentation is comprehensive and rich, consisting in large part of abstract shapes which combine smooth curves and jagged points. Even detail-level work such as the iron railings for balconies and stairways are full of curvaceous elaboration.
