		<summary>Beauxbatons Academy of Magic</summary>

		</p>
	</details>

	<details>
		<summary>Durmstrang Institute</summary>
		<p>You’ll certainly hear a few interesting stories at Durmstrang, seeing as this is the school that Dark wizard Gellert Grindelwald was expelled from. </p>
	</details>

	<details>
		<summary>Ilvermorny School of Witchcraft and Wizardry
		</summary>
		<p>If you fancy living a Hogwarts-style life across the pond. The founder of Ilvermorny, Isolt Sayre, always wished she could go to Hogwarts, and the school definitely seems to embody some of its traditions. </p>
	</details>

	<details>
		<summary>Hogwarts School of Witchcraft and Wizardry
		</summary>
		<p>Because you love it. But also because of its detailed history, secret passages, eccentric professors, wisecracking ghosts, lovely house-elves, talking portraits and much, much more besides. Most importantly, Hogwarts seems to have a sense of humour
			about itself, and round every corner is a new delight. </p>
