The exterior of the church is a confluence of Tuscan and Doric architecture styles, while the interior is a blend of Mosaic-Corinthian style. In contrast to the Tuscan-inspired mundane exterior the interiors are majestic with an imposing principal chapel. There are four chapels to either side of the main altar.
Although the main façade of the Se Cathedral was flanked by two bell towers, the one towards the north collapsed on July 25, 1776. The remaining tower houses five bells including the "Golden bell", named so because smatterings of gold were mixed with other metals during the bell's construction. It was also called the "Bell of Inquisition" since its tolling heralded the start of "auto da fes," the brutal part of the Inquisition process.
