BT Tower
The BT Tower, formerly known as the Post Office Tower and GPO Tower, stands as one of London's most distinctive landmarks at 177 metres tall. Completed in 1964 and officially opened to the public in October 1965 by Prime Minister Harold Wilson, it was designed by Eric Bedford, chief architect of the Ministry of Public Building and Works. At the time of its completion, it was the tallest building in London and held that distinction until 1980. The tower was built to support the microwave aerials then used to carry telecommunications traffic from London to the rest of the country, solving the problem of tall buildings interfering with radio signals. Its construction marked a significant moment in Britain's modernisation during the 1960s, symbolising technological progress and the country's telecommunications ambitions.
The tower's architectural design is unmistakably mid-century modern, featuring a cylindrical concrete structure that rises from a relatively narrow base to its full height without tapering. The building is composed of three main sections: a cantilevered equipment section at the base, the main tower shaft containing technical equipment and floors, and the distinctive top section which originally housed a revolving restaurant and observation galleries. The tower's slender profile and clean lines made it an instant icon of 1960s design optimism. The external appearance is characterised by horizontal bands of windows wrapping around the tower's circumference, creating a striking pattern against the concrete. Small satellite dishes and communications equipment crown the structure, visible reminders of its original and continuing purpose as a vital node in Britain's telecommunications infrastructure.
Culturally and historically, the BT Tower has occupied an important place in British life and popular imagination. During its early years, it was a major tourist attraction, with the revolving restaurant at the top, known as the Top of the Tower, becoming one of London's most fashionable dining destinations. The restaurant completed a full rotation every 22 minutes, offering diners spectacular 360-degree views of the capital. The tower appeared in numerous films and television programmes, cementing its status as a London icon. However, following a bombing incident in 1971 attributed to the Provisional IRA, the tower was closed to the public for security reasons, a closure that would last for decades and add an element of mystery to the structure.
The tower's significance extends beyond its architectural merit. It represented Britain's entry into the modern telecommunications age and served as a powerful symbol of scientific and technological achievement during the Harold Wilson era's emphasis on the "white heat of technology." For residents of Fitzrovia and the wider West End, the tower has served as a landmark and navigation point for over half a century. Its distinctive silhouette is visible from across London and has become an integral part of the city's skyline. The building was granted Grade II listed status in 2003, recognising its architectural and historical importance to the nation.
Today, visitors cannot access the interior of the BT Tower as it remains closed to the general public for security and operational reasons, continuing to serve its primary function as a telecommunications hub. The tower can be admired from street level and from various vantage points across London. The surrounding Fitzrovia neighbourhood, with its mix of media companies, restaurants, and historic streets, provides an excellent context for viewing the tower. Charlotte Street and Howland Street offer particularly good views of the structure rising above the Georgian and Victorian buildings that characterise much of the area. The tower is best photographed from nearby streets where its full height can be appreciated against the London skyline.
The tower occasionally opens for special charity events, offering rare opportunities for members of the public to ascend to the upper levels. These events are highly sought after and typically require advance booking and charitable donations. When such opportunities arise, they are usually announced through official channels and media coverage. The tower continues to be owned and operated by BT Group and remains an active part of Britain's telecommunications infrastructure, housing radio, television and telecommunications equipment.
An interesting aspect of the tower's history involves its "official" status during the Cold War era. For many years, the tower was considered an official secret under the Official Secrets Act, and it did not appear on Ordnance Survey maps despite being one of the most visible structures in London. This quirk of bureaucratic secrecy became something of a running joke, as the tower was obviously visible to anyone in central London. The revolving restaurant section, during its operating years, inspired similar structures around the world and was the setting for various social events and even some political dinners. The tower has also appeared in numerous works of fiction, from Doctor Who episodes to various spy thrillers, often playing on its Cold War associations and telecommunications role.
The tower's illumination scheme has evolved over the years, and it now features LED lighting that can be programmed to display different colours for special occasions and causes. This has allowed the tower to participate in various awareness campaigns and celebrations, making it an active participant in London's civic and cultural life despite its closure to casual visitors. The structure underwent significant renovation work in the 2000s to upgrade its telecommunications equipment and ensure its continued operational viability well into the twenty-first century, demonstrating that this 1960s icon remains relevant in the digital age.
