Museo de San Isidro. Los orígenes de Madrid

Dedicated to the city's patron saint, the well-digger and labourer San Isidro, this museum sits on the spot where he supposedly lived and performed one of his most famous miracles: when his son, Illán, fell into a well, Isidro made the water rise and thus was able to rescue the unfortunate lad. The well - or a well, anyway - is preserved inside the house, as is the chapel built in 1663 on the spot where Isidro allegedly died. According to legend, he was originally buried here too. This is, then, a museum that deals in legends as much as in solid artefacts, and the current material on show is a little limited. More interesting are the finds from local archaeological digs, formerly kept in the Museo Municipal and now in the basement here. They include items from lower-Palaeolithic settlements in the area, as well as artefacts from the Roman villas along the Manzanares, from the Muslim era.
