The Basilica di San Marco, better known as St. Mark's Basilica, is the religious center and one of Venice's most important landmarks. Located at the end of the majestic St. Mark's Square, this Byzantine-Gothic cathedral exudes an almost mystical splendor. The building, which has been expanded and embellished repeatedly over the centuries, once served as the Doge's private chapel and symbolizes the wealth and power of the Serenissima.

The cathedral is famous for its over 8,000 square meters of mosaic floor, which has earned it the nickname "Golden Basilica" (Chiesa d'Oro). The shimmering gold mosaics depicting biblical scenes and legends amaze every visitor. Another highlight is the Pala d'Oro, a masterful altarpiece made of gold, precious stones, and enamel, considered one of the world's most valuable art treasures.

Visitors can not only admire the impressive architecture and artwork inside, but also climb the Loggia dei Cavalli to see the famous horses of St. Mark's and enjoy breathtaking views of St. Mark's Square. Since St. Mark's Basilica is extremely busy, it's recommended to arrive early in the morning or late in the afternoon and purchase tickets online in advance.
