Introduction to the Horta Maze Garden: The Horta Maze Garden is located in the foothills of the northern suburbs of Barcelona. It was a private garden before it was opened to the public in the 1870s. There is a carefully tailored maze of trees in the middle of the garden, and it is easy to get temporarily lost while walking in it. There is also a pleasant man-made lake, a neoclassical pavilion and an ingenious fake cemetery. The famous German movie "Perfume" was filmed here.
