The library does not form part of the tour of the Gaudí House Museum. Anyone wishing to consult the library collection should arrange an advance appointment.

According to oral sources, this was the room where Gaudí made his models and drawings. Later, when the Chiappo family lived in the house, it was converted as part of the housekeepers’ residence. Today, it houses the Enric Casanelles Library in honour of Enric Casanelles i Farré (1914-1968), the secretary of Friends of Gaudí who played such an important role in disseminating the architect’s life and work.

One door in the library leads to the terrace roof, where there are two chimneys adorned with coloured trencadís mosaics, and which commands views over Park Güell and the city of Barcelona.

For reasons of safety, conservation and accessibility, the tower is not open to the public.

The tower is reached from the second floor by a wooden spiral staircase with a simple iron banister. At the end of these stairs is a space surrounded by windows, commanding a 360-degree view over Park Güell and the city of Barcelona. The tower is crowned by a green, conical roof.
