Nine of the new-generation shelters fitted with interactive screens that as act as advertising billboards have been installed along Princes Street, in the first phase of the development.

Designed by world renowned architect Lord Norman Foster, the new digital shelters comprise 84 inch digital screens, the biggest of its kind.

The screens are built with touch-screen technology that provides advertising and real-time information about local services for residents and tourists.

Edinburgh is also upgrading 350 advertising bus shelters, also designed by Norman Foster, the architect behind Wembley Stadium and the Greater London Authority Building.
