A major new exhibition at Bosworth battlefield will be delayed after the main contractor went out of business.
The centre aims to bring the medieval world to life
The £1.35m visitor centre will contain interactive displays and films telling of the 1485 battle which established the Tudor dynasty in England and Wales.
But since the firm overseeing the work folded just weeks from completion, plans have had to be reorganised.
The centre, which had been due to open at the end of July, is now expected to be finished in the autumn.
Alan Morrison, head of community services for the county council, said: "We are going to be working with all the suppliers and the sub-contractors to pull this together.
"We are hoping this will not add to the cost but it is a question of whatever it takes to get it up and running."
He added that he would be "very disappointed" if the situation was not resolved by the end of November.
A medieval village is also being built on the site and this is on course for a late summer completion.
The centre is located on the traditional site of the battle at Ambion Hill near Market Bosworth but some historians have placed the true battlefield closer to the Warwickshire border.
