After many years of deterioration, the City of Madrid undertook the rehabilitation of Frontón Beti Jai, a 19th Century Basque Handball Court located in its heart, Calle del Marqués del Riscal, 7 28010 Madrid. It was built in 1893-94 by arquitect Joaquín Rucoba and it worked as a fronton until 1919. The City of Madrid bought it in 2010 and it was declared Cultural Interest Heritage in 2011. It went through a serious degradation process until a citizen platform began to fight for its recovery (video IdealistaNews).
