 The vertical orientation of the interior is emphasized by the pillars supporting the dome.Attached to the pillars are several faceted pilasters and half-columns which form, at the top, semi-circular and pointed arches bearing the supporting girth of the domes.High niches, semi-circular in the plan, framed with graceful arcatures on twin half-columns, which decorate the bottom of the altar apses, harmoniously fit in with the pillars.
