Sadly, today, January 2025, the rotating door is "inobra" which apparently means "not working". You have to go into the church, and a friendly nun will serve through a metal gate, your treats. A neat little wooden box. 7E for small sweets, basically cooked egg yolks with a hard, sweet cap. Very sweet.
It's a donation. I suppose 400 years of rotating, the door needs a rest.
