Two churches in Seville. Church of San Salvador has 3 tickets and tours to book; Seville Cathedral has 60 tickets and tours to book. The table and the two notes below put them side by side; the full pages have what to see, the ticket and the timing for each.
The Church of the Saviour stands on a lively square in the centre of Seville, a ten-minute walk north of the cathedral, and it is ticketed; the ticket is combined with the cathedral and the Giralda, so buying it here, where the queue is usually short, lets you skip the long line at the cathedral itself. That is one of the most useful practical tips in Seville. An audio guide is available.
One ticket covers the cathedral, the Giralda tower and the Church of the Saviour a few streets away, which is a better deal than it first looks. Buying online avoids a queue that regularly wraps around the building by mid-morning. A guided tour costs two to three times the basic ticket and is worth it mainly for the rooftop version, a separate product that takes small groups up onto the vaults and buttresses on a route you cannot walk alone; it sells out well ahead.
