Raichle's Palace in Subotica was constructed in 1904 as a family palace for the Serbian-Hungarian architect Ferenc Raichle. It's one of the most beautiful buildings in Serbia. 

The mansion is one of the most prominent achievements of Hungarian art-nouveau, along with the Subotica Synagogue and the Town Hall. The stylized, heart-shaped iron gate is surrounded by decorative walls and colorful façades. The ubiquitous heart motif, made of ceramics, murano mosaic, wrought iron, carved wood and other materials, always appears on the balcony railings and floors. 

In the past, the palace contained the architect's office on the ground floor and a dining room. Inside was also a winter garden, a smoking lounge for men, numerous bedrooms, bathrooms, and dressing rooms. Four years after moving in, Raichle went bankrupt and the palace along with the furniture, luxurious items, and art were sold at auction.

Since 1970, the palace is home to the Modern Art Gallery of Subotica.
