Many visitors head to Zagreb's Lower Town because it is home to the capital's most prominent buildings and museums. This includes the Mimara Museum, a fascinating cultural institution housed in a stunning late 19th-century building. Inside is a rich and diverse art collection that includes artistic endeavors from the ancient world, as well as art from the Middle Ages to the 20th century. Stroll through the wide airy streets and see the architectural highlights of the Lower Town. Amidst gray office blocks and apartment buildings in the district, there are several true gems, such as Kallin’s house, located on the corner of Masarykova and Gundulićeva streets. This is a residential building that opened in the early 20th century and is considered a good example of Art Nouveau style architecture, a branch of Art Nouveau.
