The magnificent stone church of St. Lazarus is a hidden treasure of architectural beauty, located in its own square in the city center and lies over the tomb of the saint. Built by Byzantine Emperor Leo VI in the 9th century, the church was restored in the 17th century. Although the three domes and original bell tower of the church were destroyed in the first years during Ottoman rule, the gold-covered iconostasis has survived today and is a superb example of baroque woodcarving.
Next to the church you can find the Byzantine Museum, which exhibits admirable religious icons, relics and artefacts.
