Cultural tourism often brings to mind grand cathedrals and monumental temples – yet Spain is also home to the smallest church in the world. Hidden inside Colomares Castle in Benalmádena (Málaga), the Church of Saint Elizabeth of Hungary measures just 1.96 square metres. Despite its tiny size, the chapel holds a unique place in architectural history and is recognised by the Guinness World Records, combining exceptional heritage value with a remarkable curiosity.
