"The Royal Botanic Gardens in Kew in south-west London are the home of the largest collection of plant species in the world. The fame of the park is also based on the greenhouses that were erected in Victorian times. These have now been complemented by a further structure: The Sackler Crossing, named after Mortimer and Theresa Sackler, who financed the construction of the footbridge through their foundation. The bridge spans the larger of the two artificial lakes in the western part of the gardens. From a distance, it is scarcely visible, for the 25 mm slender bronze balustrade posts ensure a sense of transparency; and with their shimmering play of colours, they are also perfectly integrated into the surroundings."
