Once the royal gardens, the Burggarten is a public park, with lots of grass and trees. As we entered, we immediately walked by the Palm House (also known as the Glass House) was built in the early 1900s. It has three sections, one used as a greenhouse, one as a butterfly house, and the middle one as a cafe. Certainly lovely to look at! On the Sunday afternoon we were there, the park was filled with families and couples sitting on the lawn, playing, sleeping, reading, eating, and people watching.We walked about to see some of the sites, notably the statue of Franz Josef I, the long-ruling Emperor of the Austro-Hungarian Monarchy, and the Mozart Monument, which was surrounded by people shooting selfies and group photos in front of it. We grabbed a spot on the lawn to relax and enjoy the day!
