对角巷
对角巷（dlagon alley）
对角巷是《哈利波特》中最重要的一条魔法世界的街道（估计就和北京王府井，上海南京路概念差不多）。隐藏于伦敦破釜酒吧（leaky cauldron当然麻瓜看不见个酒吧）后的小天井中，通过用魔杖敲打垃圾箱边上的墙砖可以进入。这是一条鹅卵石铺砌的街道，多家魔法世界一线品牌商店都在这里有“旗舰店”，包括古灵阁（gringotts相当于银行），咿啦猫头鹰商店（eeylops owl emporium）,摩金夫人长袍专卖店（madam malkin's robes for all occasions）,丽痕书店（flourish and blotts）,奥利凡德魔杖店(ollivanders:makers of fine wands since 382b.c)等
