Madrid's cathedral took over 100 years to build, due to political conflicts, wars and a lack of financial resources. According to legend, it's named after the Virgen de la Almudena, whose icon was found during the Reconquest hidden in a house that the Arabs called al mudena. The building's exterior is an example of eclectic 19th-century design. The doors are bronze and there's an image of the Virgen (now Madrid's patron saint) on the façade. The interior is full of light, benefitting from the stained-glass windows and multi-coloured ceiling. Its grand Grezing organ gets played on Sundays, holidays and the day before holidays.
