On Upper Dock Street is the Chartist Tower, a 15-storey office block, built in 1966 and the tallest building in Newport. It features a secure underground car park. Radio transmitters and mobile phone masts are situated on the roof. During the 2014 NATO summit a security forces command and control team was housed temporarily in the building, with the top floor and roof being used as an observation post. In 2017 the building was sold as party of a £6.5M deal and is planned to be developed into a 163-bed Mercure hotel.
