The Richard III Centre in Leicester has been closed to the public for two weeks to allow changes to be made to the exhibition.
The attraction, at the site in St Martin's where the last Plantagenet king's bones were unearthed, closed on Sunday January 4.
Visitor centre director Iain Gordon said the closure was to allow the team to make some minor changes to the attraction, including updating information and working on sound levels.
He said: "Since opening at the end of July we have welcomed over 30,000 visitors and we have asked them to let us know what they thought about their visit.
"As a result of comments received, we're going to make some tweaks to the sound and light levels within the attraction, as well as taking the opportunity to update some of the content."
He said visitors' feedback had allowed them to identify minor changes which could be made at the city centre attraction.
He said: "We have listened very carefully to what our customers have told us.
"The comments have identified places where the customer experience can be improved by us turning up the sound a bit and lowering it in other places.
"This tweaking process also applies to the lighting in parts of the exhibition.
"The feedback has also identified the need for more signs in some places.
"That is a difficult balance to achieve because we didn't want to intrude on the experience but the comments have indicated that the extra sign here and there would be helpful."
Mr Gordon said there was also snagging work to be done on the building itself.
He said: "We are very happy with the way things have gone so far. We are on track to achieve a total of 100,000 visitors in the first year of opening."
He said the centre had opened on July 26 last year and had only previously been closed on Christmas Day and New Year's Day.
City Mayor Peter Soulsby said: "The visitor centre has been amazingly popular, and has rightly been described as 'state of the art', even by the BBC on Radio 4.
"I expect it will continue to be enormously well attended, especially overs the coming months in the run up to the king's reinterment."
Leicester Cathedral will receive the remains of Richard III on Sunday March 22.
The centre is due to re-open at 10am on Saturday January 17.
