Hogwarts is beautiful during any season. The multicolored leaves of Fall. The blooming and new life of Spring. The amazing freedom of Summer.
Winter is amazing in its own special way. The snow softens the sharp edges. The bundled cloaks allow for anonymity but for wisps of color from scarves proclaiming house affiliation.
Be it snow ball fights, Christmas Eve parties, or snuggling by the fire with your chosen someone. Hogwarts castle has seen the passage of season for countless years, yet the winter still has a certain charm. One simply needs to look out the windows to see it.
