The intriguing, odd-shaped glass building at the entrance to Baltimore's lovely Druid Hill Park is The Conservatory. The Victorian-era building has grown from its original 1888 Palm House to include four greenhouses and outdoor gardens. The Conservatory continually showcases plants from around the globe and offers special seasonal floral displays. The Conservatory offers a nice respite from a busy and probably noisy day at the nearby Baltimore Zoo, also located in Druid Hill Park.
