Built in 1892, this steel viaduct used to bring heavy rail traffic in and out of the Great Northern Warehouse, but has been unused since 1969.It has now been reclaimed for public use and turned into a ‘sky garden’ by the National Trust. It recently opened, allowing just 100 people per day to have a guided tour and give their feedback.One of our team recently visited the site and the planting was stunning as expected, with trees chosen for their specific historical uses, as well as lots of bountiful flowering borders.It’s brilliant to see another visitor attraction which gives city dwellers the opportunity to see greenery
