If something big is planned for Swansea, there's a good chance someone will have done an artist's impression of it.

Artist's impressions are just that - an artist's idea of how something that isn't built yet, might look.

Sometimes the picture becomes reality, other times it just ends up as one more dream not fulfilled.

There have been plenty of artist's impressions done for things in Swansea over the years.

Some happened, some didn't, and some might still be yet to come.

Here's a look back at how Swansea has been seen through the eyes of the dreamers...

Castle Quays

Castle Quays was the big hope for the city centre, that never happened.

First seriously considered around the time Tony Blair's New Labour came to power in 1997, it would have seen most of the existing shops and offices west of Castle Street and bounded by Park Street, The Strand, The Kingsway and Oxford Street, demolished, to make way for a new shopping mall on two levels.

But the plans eventually petered out to nothing.

Now we wait with baited breath if the latest proposed revamp of the city centre - the St David's development, can be delivered.

The old 'new' city centre

These images were part of a fly-through video of a possible future for Swansea, which would have been delivered by developers Hammerson and Urban Splash.

It would have seen large areas of the city centre revamped with new retail and residential developments.

The £1bn scheme was first unveiled 10 years ago, but just a year later in 2009, Urban Splash had pulled out, over issues with residential elements of the project.

Then, in 2013, Hammerson quit the project as well, meaning it was back to the drawing board for the city centre.

The old Walkers Crisps site

Houses were due to be created on the site

The old Walkers Crisps factory is one of the most familiar buildings in Swansea, with its tall central tower which is visible for quite a distance around.

Walkers left there following an announcement in 2005 with the loss of 250 jobs, the work transferred to other sites in Peterlee, County Durham, Skelmersdale and Lancashire.

In 2010, London-based Dundonian Holdings Ltd applied to build homes at the site.

But so far, the development pictured above has not emerged, and the building is now occupied by another business.

Salubrious Place

This is how Salubrious Place was hoped to look

There were plans to turn Salubrious Place into a 'bustling al fresco dining area', with new seating, lighting, planting and canopies to protect diners from the elements.

The proposal was put forward in 2014 to 'enliven the area'.

Currently, Salubrious Place remains much as it was.

The new Port Talbot FC stadium

These artist's impressions emerged in 2014 and were for a new stadium for Port Talbot FC, along with a community leisure facility in the docks area.

Club director Tim Bull said at the time: “The board feel the new stadium presents a once-in-a-lifetime opportunity to provide high quality and sustainable facilities and opportunities for learning and training as well as sport and fun for everyone in the area.

“We will be adopting a unique eco-friendly approach using solar panels and other environmentally friendly methods to provide energy and that could even incorporate the cost effective hire of electric cars for local residents.”

Questionnaires were sent out for people to give their views on the plans, but there's no new stadium as yet.

The outdoor climbing wall at the LC

A planning application was submitted in 2014 for a climbing wall which would seem to grow out the sides of the LC building in Swansea.

Swansea Council was behind the idea which would have seen the wall managed by the LC and the Clydach-based Dynamic Rock Indoor Climbing Centre.

“When not in use, the wall will be closed up, a flat, and beautiful mountain facing the city,” said the application.

There is no sign of the 'mountain' so far.

Work is currently taking place to strip back Mumbles Pier and restore it so it's fit for another few decades.

But the work is expensive, so as part of a £3.2m project, the foreshore area near the pier will be developed to include a hotel and apartments.

A number of artist's impressions have surfaced over the years since work was first proposed, with the designs being tweaked over time.

Work is hoped to start on the wider development around the pier in 2019, and Swansea Council recently approved plans, but the Welsh Government may have the final say.

Swansea Bay Tidal Lagoon

If you aren't familiar with these artist's impressions, then you've been living under a rock.

No matter though, as artist's impressions are what they remain and possibly all they will ever end up as.

Sadly, despite the Hendry Review backing the idea of a lagoon for Swansea, the UK Government decided not to support the project.

The £1.3bn scheme would have generated power through the incoming and outgoing tide and supplied enough electricity for 155,000 householders, according to projections.

It would also have been a pathfinder project for other larger lagoons elsewhere in Wales.

Mark Shorrock, chief executive of Tidal Lagoon Power, is still hoping to resurrect the project by hooking up cables to supply electricity directly to homes and organisations in Swansea.

The gondolas

If New Zealand-based Skyline have their way, there will eventually be gondola rides carrying people to the top of Kilvey Hill overlooking Swansea.

There, they will be able to enjoy a meal in a hilltop restaurant, before taking a luge ride down.

The proposal is at an early stage and the original costs were higher than anticipated, but the Skyline team are now said to be happier with the anticipated final bill for the development.

Hafod-Morfa Copperworks

Swansea was once world famous for its copper.

But like many industries of the past, it died.

The remnants are still there, however, and recently the Heritage Lottery Fund handed over £3.5m to help turn what's left into a visitor centre and whisky distillery.

Penderyn plans to be part of the development which will preserve the site for future generations to see.

Kingsway

Kingsway is possibly the most dug-up road in Swansea.

It has been torn apart multiple times, including for the introduction of the Bendy Bus.

Most recently, work is taking place there as part of plans for a Digital District which will include offices, public areas, and landscaped park land.

The work saw the demolition of the beloved old Oceana nightclub.

And some things that did happen...

Swansea University Bay Campus

How it was imagined the Swansea University Bay Campus would look

The Swansea University Bay Campus has been a dramatic new addition to the drive into Swansea from Neath Port Talbot.

It dominates Fabian Way and is still evolving with new buildings being created on the site.

Currently, the campus, which opened in September, 2015, is home to more than 700 staff and approaching 6,000 students.

Coastal Housing's Urban Village

Begun in spring, 2012, Coastal Housing's £25m Urban Village transformed a large chunk of High Street and revived the area's fortunes somewhat.

High Street had been seen as a run-down area of the city, but has since greeted a number of new businesses and outlets, ranging from galleries to cafes, hair salons and simulated sports venues.

Social housing provider Coastal built flats, offices, retail and creative spaces in its Urban Village.

Parc Tawe

Parc Tawe was the subject of several different plans over the years.

It ended up virtually empty as businesses gradually quit.

But the area has been transformed now with new businesses moving in including Denny's and a Costa drive-thru.

There are still empty units there however.

Oyster Wharf

How Oyster Wharf was forecast to look
And how it ended up

We waited decades for something to happen in the Oystermouth Square area of Mumbles, with a number of plans coming and going over the years.

But a development did eventually come to fruition on the site, taking over the old Tivoli and other buildings, and creating a destination venue with restaurants and cafes.

The area is now buzzing in the day and during the evening with people taking advantage of venues including Prezzo, Bistro Pierre, Croeso Lounge and La Parilla.
