Casa Batllo (Batllo House), Barcelona (must see)

Batlló House, located in the heart of Barcelona's prestigious Gràcia Boulevard, is one of Gaudí’s most celebrated architectural masterpieces. Originally built in 1877 by Lluís Sala Sánchez, the building underwent a radical transformation in 1904 when textile industrialist Josep Batlló hired Antoni Gaudí to renovate it. Gaudí expanded the structure, creating new floors and adding his signature audacious design, which turned this previously unremarkable building into a landmark of Modernist architecture.

Batlló House is often referred to as the "House of Bones" due to its skeletal-like balconies and organic forms. Another local name for it is the "House of the Dragon," as its arched roof, covered in colorful mosaic tiles, is said to resemble the spine of a dragon. This symbolism aligns with the legend of Saint George (Catalonia’s patron saint), whose lance is represented by the turret and cross atop the roof.

The building's façade is divided into three sections and adorned with vibrant broken ceramic tiles in shades transitioning from orange to greenish-blue. Gaudí’s use of curves, irregular windows, and sculpted stonework avoids straight lines, enhancing the structure’s flowing, dynamic feel. Inside, the loft space, with its catenary arches, imitates a ribcage, while the central atrium features blue tiles that create an underwater-like light distribution.

The rooftop is a highlight of Batlló House, with its chimneys resembling twisted, tiled sculptures. The entire structure integrates symbolism and decorative elements that showcase Gaudí’s innovative approach to form and function. After the Batlló family left in the 1950s, the house changed ownership several times and was refurbished before becoming a venue for events in 1995. In 2005, Batlló House was designated a UNESCO World Heritage Site, cementing its status as a masterpiece of modernist architecture.
