Jubail Mangrove Park

This guide to Jubail Mangrove Park in Abu Dhabi opens with Prince William kneeling in the mud to plant a seedling alongside local schoolchildren, on the same tidal mudflat that holds most of the UAE's remaining mangrove forest. It follows the Danish architects at CEBRA and their deliberate choice to build almost nothing, scattering small learning nodes along a boardwalk that floats above the roots rather than disturbing them. Look down through the slats as you walk for the crabs working the mud between the roots.
