160,000 bees living above Liverpool ONE
Honey bees don't just flourish in people's back gardens or the countryside, they thrive in urban environments just like Liverpool ONE.
Two beehives were added to the roof of Barclays Bank on Lord Street in 2019 as part of Liverpool ONE's commitment to green initiatives in urban environments.
The shopping centre joined forces with horticultural experts, Nurture, and John, master beekeeper at Nurture and have been keeping an eye on the bees ever since.
As well as the hives, 'bug hotels' with 12 species of insects have also been added to Chavasse Park to give them shelter during the winter months.
Both initiatives nurture biodiversity the local environment and are part of our ongoing commitment to Liverpool ONE becoming greener.
Secret streets above the city
In the 1960s there were plans for Liverpool's "walkways in the sky", a network of raised pedestrian walkways which were partly built in the 1970s.
Most of the walkways have gone, with just traces remaining.
But some of the streets remain, inaccessible to the public, round the back of the Capital Buildings – with street signs still up.
King Edward Parade connects to Queen Anne Parade along the side of the Capital, which was built as the home of Royal Insurance and was only accessible on foot via the elevated walkways.
You can still get to another sky terrace – Atlantic Terrace, around the first floor of the Atlantic Tower hotel.
'Lake' and viaduct below the city centre
This mysterious "vault" lies below Water Street and the Pier Head in Liverpool city centre.
An engineer working for the council sent the ECHO this picture, which shows a "lake" of clear water below the arches.
The vault is regularly inspected by council engineers. It’s a remnant of a viaduct built to hold up a road above that was later buried as more land was reclaimed.
A mysterious spring with "haunted water" in an old church
Liverpool’s only natural spring has been shrouded in mystery for almost 250 years with some people believing that the “haunted water” turns black when you boil it.
The Chalybeate (contains iron) spring in St James’ cemetery was discovered in 1773 by a group of quarry men on the eastern side of the graveyard that is overlooked by Liverpool Cathedral.
Due to the notoriety of St James’ cemetery as one of the most haunted sites in the UK many myths have circulated over the “bewitched” spring and the healing qualities of the water it produces.
Others believe that the spirits trapped inside the graveyard have contaminated the water so that it turns black when you boil it.
The source of the spring is still unknown but stories have circulated over the years about how the cool waters can relieve fevers, diarrhoea, symptoms of diabetes and gout.
Although we wouldn’t recommend you drink from it.
There's an old dock you can visit below John Lewis
Every day people walk through Liverpool city centre and, unbeknown to them, beneath their feet is an amazing old dock and the creek from which the city's name derives.
The Old Dock was the world's first commercial wet dock and the creek which the dock was built on is a rare natural inlet coming in from the River Mersey.
These hidden gems have been preserved underneath Liverpool ONE, and Merseyside Maritime Museum showcases them on FREE tours.
The revolutionary Old Dock was discovered during excavations in 2001, after being buried since 1826.
Liverpool has a set of stones older than Stonehenge
While visitors flock in their millions to witness the prehistoric ring of Stonehenge, we actually have our own set of stones which were once a part of a chartered tomb.
The six sandstone blocks known as The Calder Stones, now housed in Calderstones Park, are believed to be Neolithic and constructed before Stonehenge, at some point between 10,000 BC and 4,500 BC.
Little was known about them until the 18th century when they are thought to have been disturbed.
