The interior of the cathedral was divided into 3 aisles, 2 rows of six cylindrical columns that flank the central aisle. At the end of the aisle is a polygon aps and there you can see two square towers adorning the façade. On the top part of the façade there was a huge pointed window which was decorated with carved floral motifs. However, on the North and South wall there were windows with simple openings and of course the pointed ends we showcased with these too.
The whole entire building was once covered with pointed domes that were formed by pointed groin vaults that’s started from the building’s columns. Inside the Cathedral it had paintings which were destroyed during by the Ottomans during the change of the Cathedral to a Mosque. This happened in 1571 and the Cathedral received a white wash and the addition of a minaret was built. The sculptures were destroyed, some traces of the paintings on the wall were still visible even though they were destroyed. Even the crucifix was destroyed in the conversion. The sained glass was also destroyed but fragments were preserved of the gorgeous stained glass on the south aisle.
