It's not a box, but a series of them - and it's not a park - at least not in the slides-and-swings sense of the word - but Boxpark is more than worthy of your attention.
Why, you wonder? Well, first of all, it is the first thing you will see as you exit Shoreditch High St train station, and second, it is probably the most compact shopping mall you will probably ever find.
The reason for this is simple, each retail unit is housed inside a stripped out shipping container, with the units decorated according to the shops that occupy them, creating an interesting and dynamic retail solution - which also happens to be the first of its type in the world.
It really does have everything - on the ground floor you can find clothes shops, galleries, and quirkier products which you may not be able to find in larger retail spaces. Upstairs you can find cafes, bars and restaurants. The site really is an interesting juxtaposition of well-known brands doing something new, to local brands on their way to bigger things.
As well as all this, the Boxpark regularly supports events, which are usually hosted by individual units, or involve collaborations between particular areas. These events are well worth looking at, matching the creativity of the area, and themed around such ideas as gallery launches, dating nights, and even the worst films ever made (of which I may try to make it to...)
Of course, the internet is probably an even more convenient way to do your shopping - but, nowhere near as much fun - so I think I know which I prefer...
