Alnwick is a market town in Northumberland. And, although the population is not that large, there is much to do and see in Alnwick. Film fanatics love to visit this part of the country, as Alnwick Castle has made its stamp on the big screen. Featuring as Brancaster Castle in multiple episodes of the Downton Abbey series, and perhaps most significantly as Hogwarts School of Witchcraft and Wizardry in the first two Harry Potter films, many tourists love to visit this castle – it's no surprise that this castle is quite literally spellbinding to visit. If you have some spare time you should take a visit to the Alnwick Garden, which is one of the most beautiful in the UK. It holds over 4,000 varieties of plants, a mysterious poison garden full of deadly spieces, and a seasonal cherry orchard as well as the largest collection of Japanese Taihaku cherry blossoms in the world.
