Allen Centennial Gardens is a beautiful botanical garden on the University of Wisconsin–Madison campus. Filled with stretches of lush green trees, flower beds and landscaped lawns, this is one of the most appealing sites in the city. While it is mainly used as an outdoor classroom for students of agriculture and botany; the garden also is open for public recreation. Its cobbled paths, serene atmosphere and colorful backdrop makes it perfect for a quiet walk in the day. The garden also hosts a number of artistic and educational events, and portions of it can also be rented out for private functions.
