Watch: BT Tower's memorable moments as part of London's skyline - TV cameos to announcing royal babies

Following the news that the BT Tower will be transformed into a hotel, let's reminisce about the London landmark's six decades as part of the capital's skyline.

This week, it was confirmed the 177m structure will become a new place to stay in the city following a £275m sale to MCR Hotels.

Having been completed in 1964, over the years the building has become one of London's most iconic landmarks, having appeared on both TV and film and even announced the birth of a few royal babies.

Despite it being a familiar capital sight, you may be surprised to hear it used to be an offence to take a photo of the now iconic tower. When it first opened as the Post Office Tower, until the mid-’90s it was technically classified as an official secret.

It later ended up being catapulted into pop culture history, featuring in the popular series' Doctor Who and The Goodies as well as the Harry Potter movie franchise as Harry and Ron fly over it in the Weasley family car in the Chamber Of Secrets film.

In 2011, the building's unique architecture became a giant lightsaber to mark a Star Wars Blu-ray release.

Having announced the births of Prince George, Princess Charlotte and Prince Louis and projected the late Queen Elizabeth II’s first tweet on its LED screen, promoting a Science Museum exhibition, the landmark has also featured in royal history.

In recent years, the structure has become known for its annual countdown to the new year.

We don't doubt the spot will have plenty of memorable moments in its new chapter as a hotel.
