Introduction to the circular pavilion: There is an exquisite circular pavilion at the entrance of the Botanical Garden, designed by Lorenzo Castro and Ana Elvira Vélez. A group of 20-meter-high wooden mesh canopies hang over a grid-like courtyard. It contains 10 hexagonal flower tree structures that collect fresh rainwater and bring them together like a honeycomb to form a safe barrier for orchids and butterfly sanctuaries. This canopy has immediate economic benefits and is also a beautiful sight.
