The base of Mount Arera in Nothern Italy has just moved up to the top of my travel bucket list. It is where Italian artist Giuliano Mauri built the framework for his Cattedrale Vegetale, a cathedral-like structure formed by weaving more than 600 chestnut and hazel branches around 1,800 fir tree poles to form 42 columns. After each of the columns deteriorate, a single beach tree – planted inside each column – will outgrow the structure and create a natural wall and roof. In just a few more years, the end result will be a Gothic-like cathedral make entirely of trees. Honestly, wow.
