Central-North Dome

Central-North Dome is one of the domes of the London arcology, the first to be erected: as of 2070 it was already completed. It consists of an amber translucent geodesic roof on comparatively tiny struts and fitted with ten large exhaust vents. With a diameter of 4 km, it covers most of Westminster. Key structures are made from orbit-grown superstrong materials, this being on one of its first large-scale uses.
