Stock Photo - 24 April 2020, Spain, Barcelona: In the middle of the Corona crisis, a cyclist rides through an empty street past the ""Casa Mila"" by the Catalan architect Gaudi. The streets of the city, otherwise flooded with tourists, have become empty in the wake of the Corona pandemic. Overnight stays in Spanish hotels and guesthouses in March 2020 fell by 61.1 percent compared to the same period last year due to the corona crisis. The slump is likely to be much more severe in April because the closure of hotels in March was only ordered on 19 March with a transitional period of seven days. Spain, which has been particularly hard hit by the Covid 19 pandemic, is heavily dependent on tourism. Photo: Matthias Oesterle/dpa. - Barcelona/Spain
