The last 20 years have seen huge changes in the county, with new landmark buildings for Canterbury and Margate, and massive infrastructure projects like HS1 and the Sheppey Crossing changing the way we travel.

But it's not just what Kent has gained. As the county's needs have changed, so has the built landscape.

Massive power stations that once dominated the countryside for miles around have been levelled, while the London Array has sprung up off the coast. Here are ten of the bigest changes Kent has seen in the last two decades.

Sheppey Crossing

The Sheppey Crossing was opened in July 2006, and finally provided a reliable way to get on and off the Isle of Sheppey, uninterrupted by boats travelling down the Swale.

But it has not been without controversy. The design of the bridge has been criticised by safety campaigners and was even blamed for the UK's biggest car crash in September 2013, when 150 vehicles were involved in a pile-up on the bridge in heavy fog.

Various solutions have been discussed and the speed limit has now been reduced to 50mph.

Marlowe Theatre

The Marlowe Theatre first opened on its current site in 1933 in the former Friars Cinema. But the size of the venue meant it could not attract the largest productions, and plans were drawn up for a replacement.

The old Marlowe Theatre closed its doors in 2009, and construction began on a modern building designed by architect Keith Williams.

The 'iconic' building was not without its detractors, but with a larger capacity has allowed big West End productions to be performed in Canterbury for the first time.

Bluewater

What was once an abandoned quarry has been transformed into one of the largest shopping centres in Europe.

Attracting 27 million customers every year from Kent, London and Essex, love it or hate it, Bluewater is hard to ignore. For a start, it's massive - the site is 240 acres and the mall has 1,600,000ft of retail space.

And it's a major employer, providing about 7,000 jobs. Since opening the centre has gone from strength to strength and is even planning an expansion.

Turner contemporary

The Turner Contemporary was intended to revitalise Margate, drawing on the town's cultural history to attract tourists from across Kent and the south east.

Built on the seafront, on the same site as Mrs Booth’s guest house, the gallery is the largest art exhibition space in the south east outside London.

It opened in 2011 and has since attracted nearly two million visitors.

Sittingbourne paper mill

Sittingbourne was once famous for manufacturing paper, and a mill existed on the town centre site from about 1769.

The mill provided paper for Fleet Street but demand eventually outgrew the site, with production slowly moving to a new mill at Kemsley, which is still operating.

It finally closed in 2007, with the iconic red brick buildings controversially demolished to make way for an enormous Morrisons.

Former airfield site, Kings Hill

The former RAF site was used as a landing area during the First World War, and became a private airfield during the interwar period when it hosted airshows and Maidstone Flying School.

With the outbreak of the Second World War it became RAF West Malling, an important airfield on the front line of the fight against the Luftwaffe.

The site continued to be used for maintenance until the 1990s, when it closed. It is now a large housing development, with the listed former control tower the only evidence of the site's aviation history. The control tower is a Costa Coffee.

Floral sheep

Anyone walking down Maidstone High Street in the mid 90s cannot help but remember the large and rather odd sheep-themed floral display.

Like many high streets in Kent, the scene has changed considerably in Maidstone since then, with an emphasis on pedestrian access and even the type of 'cafe culture' borrowed from the continent.

As for the floral sheep itself, will we ever see its like again? We just don't know.

Richborough Power Station

Richborough was built as a coal-fired power station close to the mouth of the River Stour near Sandwich which operated from 1962 to 1996.

Originally the station used coal from the Kent coalfields, but was converted to oil in the 70s.

The 97m cooling towers could be seen for several miles, a significant local landmark. They were finally demolished in 2012.

Ashford Designer Outlet

Ashford's outlet opened in March 2000, in a memorable building designed by the Richard Rogers Partnership.

The shopping destination has proved successful, and has plans to almost double in size, but some argue the effects on Ashford town centre have not been positive.

The latest plans have been granted with a number of caveats, including certain restaurants banned from opening at the outlet.
