LION Salt Works bosses have been keeping their fingers crossed that millions of viewers have backed their appeal.

About three million people were expected to tune into last night's BBC Two screening of Restoration as the Lion Salt Works in Marston went head-to-head with two other historic sites in the contest's knockout stages.

You can still have your say, because the phone lines are to remain open until midnight tonight (Wednesday), but the Lion bosses won't know whether they have made the northern final until the early hours of Sunday morning.

If the salt works is successful and goes on to see off competition from seven winners from around the UK, campaigners will collect more than £3m towards restoration plans for the site, considered to be one of 10 most important industrial archaeological sites in Britain.

Project director Andrew Fielding said: 'The anticipation is exhilarating but it also makes you very nervous. We can't wait for the result - getting through to the final would be a dream come true.'

And even if the vote doesn't go their way, members of the Lion Salt Works Trust will continue their efforts to restore the attraction.

Andrew said: 'If we don't make it, we will still continue our campaign to restore it to working order.'

If the salt works gets through, supporters will need to vote again at the live final on Sunday, August 8, when eight properties will go head-to-head.

The works is 110 years old and one of only three open pan mines left in the world.

When restored, members of the trust say it will become a tourist attraction.

Brown Owl Marina Dancy became a Lion for a day when she and the 1st Castle Brownies took Lion Salt Works mascot 'Lionel' into Northwich town centre last week to canvas support for the campaign.
