Overview

Longoria Palace, as it's also known, is Madrid's finest example of modernist architecture. Take a look at the sinuous forms of its balconies, its windows shaped like leaves, its lovely wrought-iron work and the strikingly original structure itself. It belongs to Spain's General Society of Authors and is normally closed to the public. However, you can gain access on the first Monday in October every year (World Architecture Day) when every building in Madrid opens for free. Once inside you can appreciate the spectacular staircase, its balustrade and the glass-domed ceiling.
