Now, the Hatters are just one game from returning to England's top flight for the first time since 1992 - and that'll be music to the ears of keen football ground hoppers in the Premier League.

Back in the Hatters' non-league days, as the club tried to rebuild after suffering from administration, their beloved Kenilworth Road was one of the larger grounds in the fifth tier with a capacity of over 10,000.
Home since 1905, 20 years on from the club's formation, the ground has seen all the highs and lows of Luton Town and has had many different areas readjusted at different times, with the last being in 2005, leading to its unique design.
The Hatters plan on moving to a new home, the Power Court Stadium, a former power station just one mile east of Kenilworth Road in the town's centre.

Before then, Rob Edwards' side could be promoted to the Premier League, with them currently sitting third in the Championship, with £10million of improvements to do to the ground should they go up to prepare it, according to chief executive Gary Sweet.
But aside from ticking another ground off, those Premier League fans who do get to visit Luton's current home will no doubt be desperate to witness the whacky away end everyone in the Football League has raved about since Luton's return in 2014.
The infamous Oak Road End holds around 1000 fans. But whilst the view inside the stadium is unique, it's the entrance that has left both visiting fans and those that have seen it on social media in disbelief.

The lead up to Luton's away end is lined by terrace houses, but the row of red bricks suddenly comes to an abrupt end thanks to a large blue sign over what should be the downstairs of someone's property.
Below that sign resides Luton's away turnstiles, along with stewards that reassure you you're definitely at the right place to watch a Championship game, rather than trespassing someone's home.
After having your ticket checked, fans are greeted by a blue painted iron staircase that climbs up the back of the Oak Road End itself.
And as supporters go up, the sight of peoples' gardens appears, with trampolines, washing lines and other typical garden items easily spotted on either side.

Stepping into the away end itself feels like going back in time.

But despite the ground's unusual lay out, it really is a breathe of fresh air for those fans so used to going to dustbowl-esque stadiums with no character.
Erling Haaland and co certainly won't be used to playing surrounded by such an old fashioned, higgledy-piggledy layout.
However, there's no doubt Premier League fans will be desperate to see this one for themselves.
They are just one game away from the top flight having beaten Sunderland in their play-off semi final on Tuesday night.

And as for those that never make it there before Luton's proposed move to their new, modern, 23,000 seater stadium, they really have missed out big time.
