Skaters at this park in Lugano, Switzerland don’t have to pull out their phones to check the time – they can just glance down at a series of colored lines painted right onto the concrete of the bowl as a modern sundial. A ribbon of rainbow hues curves up and down the undulating surface, the sun and shadows revealing the current hour.

A different line of color indicates each hour of the day, marked off as the sun passes overhead. Designed by Moscow group Zuk Club, the vibrant park is like an abstract modern mural customized specifically to the shape of the bowl and the surrounding area.

It’s an interesting and visually resting concept, though perhaps no match for the largest and most complex skate parks around the world. Skaters who find ordinary skate parks unimaginative should check out 13 examples of highly skateable architecture, ranging from the specially renovated interior of a hunting lodge to Zaha Hadid’s futuristic science center in Germany.
