Casa Milà is one of Gaudi's most famous works in the city. A great example of Modernist architecture, this house is a part of La Pedrera collection. You can walk down Passeig de Gràcia and admire it from the outside (best way to get a good photo), or buy a ticket, wait in line and go upstairs. I've done both and recommend both. Inside,you'll see a gorgeous apartment designed for a wealthy merchant back in Gaudi's day. On the roof, you'll see the human-looking structures towering over the street. #lapedrera #gaudi #modernista #casamila
