SINCE 1830 Traditional puff pastries and a mysterious well   Founded in 1830 by the Agudo family, it is one of the best, traditional and artisan pastry shops in Madrid, where puff pastry is still made by hand, with sheets of puff pastry filled with cream or angel hair. Located at number 6 Calle del Pozo, it takes its name from this one, which in turn owes its name to the traditional belief of a miraculous well, located on this street and into which the relics of some saints would have been thrown, made that caused “mysterious situations”
