This morning, my hiking group took a walk in the Manzanares Linear Park
The Manazanares Linear Park, created to inspire a return to nature and to recreate a traditional Mediterranean garden, is one of the most interesting architectural projects of the late 1990s and is located in the Doce de Octubre (Usera). Orchards, olive groves and the Manzanares riverbed surround the Caja Mágica (the High Performance Tennis Centre), designed by Dominique Perrault.
