Architects designing ski jumps is one of our favorite typologies, as the megastructure meets the athletic show to produce some of the most Nike-swoosh-like structures out there. Boston is going to get a new mutation of the type when a huge, 140-foot ski jump will be installed on the baseball field, in the shadow of The Green Monster. Actually, it will tower over the Green Monster by 100 feet, as well as the entire structure of Fenway. We have seen all kinds of things on fields, like Bon Jovi concerts and Monster truck rallies, but the huge snow-covered structure is one of our favorites. What is yours?
