Madrid has many Irish pubs, just as you’d expect from any city these days. This particular one claims to be the smallest Irish pub in town. It was closed when I came across it so I can’t tell you anything about the atmosphere or the libations, but I can show you its beautiful facade.
Its outer walls are covered with ceramic murals, depicting rather romantic views of the months of the year.
La Fontanilla, Plaza Puerta Cerrada at junction with Calle Cuchileros.
