Turin Cathedral, known in Italian as Duomo di Torino, is a remarkable example of Renaissance architecture, dedicated to Saint John the Baptist. It stands on the site where, in the 4th century, three early Christian basilicas were constructed. The current structure was completed in 1498 and is renowned for housing the Shroud of Turin, a relic of immense religious significance. The cathedral's bell tower, dating back to 1470, adds to the historical grandeur of the site, making it a focal point of Catholic faith and Italian heritage.
