You can’t beat a good rooftop, especially one that’s got a garden, and Crossrail Place Roof Garden is one of the biggest in London. It showcases some of the plants that were brought to the capital by explorers in the 18th and 19th centuries, and as Crossrail Place is almost exactly on the Meridian Line the layout reflects different hemispheres. You’ll find Asian plants like bamboo and Japanese maple on the eastern side of the garden, with ferns and sweet gum from the Americas on the western side. You can wander through and explore the foliage or take five on the benches nestled into the pathways.
