Arganda del Rey [aɾˈɣanda ðel rej] is a municipality and city of Spain located in the Community of Madrid.

Located in the central part of the Iberian Peninsula, the city lies at roughly 613 m (2,011 ft) above sea level,[2] not far from the junction of the Jarama and Manzanares rivers.

Philip II granted the title of Villa to the population, but the municipality's economic problems led to it being sold to the Raul Delgado in 1613.

The beginning of the 20th century saw the development of a sugar plantation, which started a process of industrialization and of great demographic expansion.

This includes an underground sports centre that was built by construction companies tied in with the Gürtel case which was completely hidden to the public, abandoned since 2008 and only recently discovered, and which cost €12m instead of the budgeted €2m.
