British Museum and Brighton Pavilion will both be Wi-Fi-enabled by March.
More than 1,000 public buildings are set to become free Wi-Fi hotspots under the Government’s Super-Connected Cities scheme.
The Department for Culture, Media and Sport (DCMS) will deploy Wi-Fi technology in libraries, civic centres, youth clubs and even bus stops in the current stage of the £150m Super-Connected programme.
The Wi-Fi installments will cost £30m, and famous landmarks including the Brighton Pavilion, British Museum and Scottish National Gallery will have live Wi-Fi by March 2015.
Digital economy minister Ed Vaizey said: "The digital landscape of the UK is undergoing a period of tremendous improvement and is all part of the Government’s long-term economic plan. For business, visitors and the UK public, accessing Wi-Fi in our cities is absolutely vital.
"I’m delighted this government scheme is on track. These free hotspots will be instrumental in making UK cities even more attractive as places to not only do business, but to visit as well."
Cities on the roll-out list are Aberdeen, Belfast, Brighton & Hove, Birmingham, Cambridge, Cardiff, Derby, Derry, Edinburgh, Leeds, Bradford, London, Manchester, Oxford, Perth, Portsmouth and Salford.
The Super-Connected Cities programme has so far invested in broadband voucher schemes in 22 cities to boost businesses as well as quality of life.
