The majestic baroque Salzburg Cathedral is the heart of Salzburg's UNESCO World Heritage Old Town. Completed in its current form in 1628 after a devastating fire, it features a massive dome, stunning frescoes, and five organs. Mozart was baptized here in 1756, and visitors can see the original baptismal font. The cathedral's vast Domplatz serves as a venue for festivals and the famous Jedermann play during the Salzburg Festival.
