The first St Mark's was a temporary building in the Doge's Palace, constructed in 828, when Venetian merchants stole the supposed relics of Mark the Evangelist from Alexandria. This was replaced by a new church on its present site in 832; from the same century dates the first St Mark's Campanile (bell tower). The new church was burned in a rebellion in 976, rebuilt in 978 and again to form the basis of the present basilica since 1063. The basilica was consecrated in 1094, the same year in which the body of Saint Mark was supposedly rediscovered in a pillar by Vitale Faliero, doge at the time. The building also incorporates a low tower (now housing St Mark’s Treasure), believed by some to have been part of the original Doge's Palace. Within the first half of the 13th century the narthex and the new façade were constructed, most of the mosaics were completed and the domes were covered with higher wooden, lead-covered domes in order to blend in with the Gothic architecture of the redesigned Doge's Palace.
