Seeing the Botafumeiro Fly
The use of a large censer or botafumeiro (loosely 'smoke spitter') in Santiago's cathedral dates from the 13th century, a time when masking the odours of road-weary pilgrims who slept and cooked inside the cathedral was more than a mere ceremonial act. Today the cathedral has two botafumeiros, one made in 1851 of silver-plated brass, the other a 1971 silver replica. Each weighs up to 100kg when filled with coal and incense, and attains a speed of 68km/h as it swings high over the centre of the cathedral, propelled by eight men tugging a system of pulleys, and reaches an almost-horizontal angle of 82° from vertical.
These days the botafumeiro flies only on certain religious feast days (listed at http://oficinadelperegrino.com/en/faqs), or at the end of a Mass if a pilgrimage group donates €300. The spectacle always attracts large numbers of people to the cathedral. When the botafumeiros are not in action, you can see them in the Museo da Catedral.
