As far as castles go, there are few as unique (and susceptible to melting) as that in Finland’s Ylläs Snow Village. Among ice wolves, crystal-clear staircases and frigid ramparts, Antti Ollila, Aleksi Patja, Miika Virkki and Eemeli Jussila find what’s possibly one of the most surreal jib spots in the world for the third episode of their “Hot Chocolate” web series. Walt Disney would approve.
