Operating undetected from Muggle’s knowledge, Diagon Alley is a bustling high street catering for wizards and witches with wares to make potions or stock on up spell crafting necessities like cauldrons, brooms and wands.

Consisting of 4 “doll-house” like buildings, Diagon Alley will thrill and delight Harry Potter fans - but the true magic of this LEGO set is realised when it is coupled with the Light My Bricks light kit that truly brings this enchanting set to life!

With the ability to arrange and connect the separate buildings anyway you like without compromising the lights, the Light My Bricks light kit gives you the flexibility to display Diagon Alley however you like, and at the same time, enhance all the unique features this set has to offer.

With 74 individual lights, including internal and external lighting, the Light My Bricks will put a spell on your Diagon Alley and make it a true centrepiece to marvel at.
