[1] Gaudí drew inspiration for Casa Figueras from the medieval castle that once stood on the same site, built for the King of Aragon in the early 15th century.

[2] When Jaume Figueres and his wife, María Sagues Molíns, commissioned Gaudí for the project in 1900, all that remained of the initial structure were a few walls and the patio.

For instance, while the building displays Gaudí's iconic mosaic detailing and incorporation of natural elements, it does not include Moorish accents and bright colors (aside from the stripes on the tower cross), which are key distinctive characteristics in much of his later works.

When Lluís Guilera Molas first bought Casa Figueres in 1944, the esteemed doctor intended to convert the building into a modernist hospital, similar to Sant Pau, dedicated to cancer treatment and research.

[2] For the past 30 years, the Guilera family has left the gates open permitting guests to stroll the gardens and observe the home's exquisite exterior.

Over the years, they received countless requests from visitors to explore inside the home and enjoy Gaudí's more modernist interior detailing.

The need for restoration was a particularly strong factor in influencing the Guilera family to open their home to the public, as they realized that in living in such a historic and architectural jewel they also assumed responsibility of its preservation.

The family officially began inviting tours in September 2013, offering access to the interior accompanied by explanations of the history and architecture.

The general structure measures a square base of 15  × 15 m and is 19.5 m high, with an area of 900 m.[4] The exterior façade is more neogothic, as Gaudí intended to pay tribute to the original medieval castle that once stood at the site.

Torre Bellesguard is perhaps what the building is most recognized for, displaying Gaudí's typical cross of four arms decorated with red and yellow mosaics to mimic the Catalan flag.
