It has dominated the Liverpool skyline for more than 50 years.
Over that time, St John's Beacon has been home to a revolving restaurant and, latterly, Liverpool's Radio City station - the latter being the name by which the tower is now more commonly known.
Despite its iconic status, the structure was only awarded Grade-two listed status last December by Historic England, in recognition of its architectural and historical qualities.

Last year, the ECHO took a closer look at this amazing landmark which continues to fascinate visitors and locals alike: a sheer concrete shaft rising from the St John's shopping centre and culminating in a flat horizontal viewing platform.
Completed in 1969, the building took five years to complete and offers striking views of the city from dizzying heights of 138 metres (or 452ft in old money).
It was the tallest building in Liverpool until the construction of the Beetham West Tower.
The beacon's main purpose at first was to act as a ventilation shaft to the shopping centre below, but the tower became famous in the 1970s for its signature revolving restaurant.
Many will warmly remember The Tower Restaurant which used to welcome customers for an unusual dining experience.
The restaurant later closed in 1978, but a viewing gallery remained open for visitors to marvel at the city from.

It reopened in 1980, however this was with a reduced capacity.
Despite various refurbishment efforts, the restaurant finally closed its doors in 1983.
It wasn't until 1999 when Radio City set up home that the tower was truly back in business - but the structure no longer revolves due to brackets being put in place to hold it still.
Lesser seen photos show what the landmark could have looked like, had original plans gone through.
Its distinctive silhouette could have looked very different as an architect's model showed a glass-walled "lantern" look.
And above the lantern, the tower tapers to a point.
Thirty years after the tower was completed, an extra floor was added to the building so Radio City could move in - giving the tower the silhouette we all recognise today.
Amazing pictures from the 1960s show workers constructing the now-iconic building as windows of the revolving restaurant are fitted.
One brave worker can be seen up a huge height with the city beneath him as he completed his work.
Hostesses who worked there in the 1970s were also pictured at work as they were hired to welcome people into the building.
The tower remained unused for a number of years, but in 1994 blue neon strip lighting was introduced to the tower.
In 1999, £5 million was spent on refurbishing the tower, the neon lighting was removed and fireproofing was added to the stairs.
As well as being a landmark the city can be proud of, St John's Beacon has also played host to historical moments through the years.
It marked 100 years since World War I on November 11, 1918, when thousands of poppies were launched from the top of the building.
