To fully comprehend the genius and radical innovation of Brussels-based architect Victor Horta (1861-1947), one must see his interiors first hand. But since out of the four famed town houses he created in Brussels in the closing years of the 19th century, only his own house and studio is open to the public, operated since the 70s as the Horta Museum, it is the only place to truly appreciate the magic of his interiors. My visit to the Horta Museum yesterday was memorable and transforming, particularly as I was lucky to get a private tour by its legendary curator Francoise Aubry, who since 1976 has cared for this masterpiece and made it into what it is today – a celebration of one of the most influential architects of modern times. Built between 1898 and 1901 at 23-25 rue Américaine in Saint-Gilles, the Museum is composed of two buildings, originally occupied Horta’s home and workplace. Within a lot of 6.3 meter width, Horta succeeded to create an-11-story spacious home that seems enormous, using his innovative support beams, where iron, mosaics, stained glass, wood paneling, and furnishings are composed into an elegant and tasteful home, and where every detail, from keyholes, to built-ins, to skylights, to the iconic staircase are tuned into a symphony of design. Mandatory for any architect, designer, or lover of design.
