After the Legacy project, the larger Serpentine Postbox will be found outside the gallery’s front door and the smaller one in the bookshop.

"We hope the postbox will still be at the Serpentine in several years. It would be nice if it stood the test of time." - Nina Tolstrup, Studiomama

"We see fewer postboxes now in public space than when I was a kid and I wanted to bring one back. We have 1.2 million visitors a year at the Serpentine so it will be a very public postbox!" - Hans Ulrich Obrist, Serpentine Galleries
