St. Stephen's (or Esteban) is one of the oldest churches in Valencia. It is built in the Gothic style on the site of a mosque that stood in the city when it was under Muslim rule. It is a rather small church, not far from Valencia Cathedral.
According to one legend the site was that of an old Roman temple dedicated to Hercules. St. Stephen's was the notaries' church. The main church is open on Sundays and Holy Days of Obligation; the chapel is open daily for mass.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
