The Guildhall welcomed its 50,000th visitor to the Richard III exhibition at the weekend.
The temporary display, which opened in February, will remain until a permanent exhibition opens in the former Leicester Grammar School building next year.
It has been welcoming an average of about 900 people a day.
Among 3,500 who have left comments in the visitors' books are people from Australia, the United States, Canada, Japan, France, Italy and Spain.
Families have queued around the block to learn about the discovery of monarch's remains in a nearby car park, in August last year.
The 50,000th visitor, 13-year-old Charlie Elwell, arrived yesterday afternoon with her mother Susan and friend 95-year-old Albert Richards.
They had travelled just over 50 miles from Walsall, in the West Midlands, because they had seen a programme about the exhibition on television.
Charlie said: "I like history and we have done Richard III at school. So it was really interesting to come to Leicester to see all about him. I love the exhibition."
Mum Susan, 49, said: "We saw all about it on the television so we wanted to come to see for ourselves.
"It is really good. We also visited the cathedral.
"It is quite a coincidence that I am wearing the white rose of York on my hat."
Albert said: "To see our history like this is very exciting."
The group was given a bag of goodies, including Richard III memorabilia, theatre tickets and a voucher for a meal.
Mayor Sir Peter Soulsby said: "It's incredible that 50,000 people have already seen this exhibition, with many of them coming from all over the world.
"There is clearly a huge amount of interest in this discovery and we will be doing our utmost to ensure our new visitor centre captures this interest and gives visitors a unique insight into the life and times of Richard III and the rich history of our city.
"It's a lovely exhibition – although it's quite small and was put together quickly, so it's just a taste of what people can expect when the full-time exhibition opens this time next year."
The exhibition at the Guildhall, which stands in the shadow of Leicester Cathedral, where the king will be reburied next year, tells the story of the dig through four narrators.
The historian, the archaeologist, the bio-archaeologist and the scientist all describe different parts of the Greyfriars project.
The exhibition also features a model of Richard's skull, on loan from Loughborough University, and a number of interactive touch-screen tours.
In the visitor's book, Jean and Les wrote: "Fabulous! I have changed allegiance from Henry VII."
"Excellent exhibition – very clear and easy to follow. We'll definitely come again," wrote Mary
Nicole said: "Very interesting and pleasing exhibition. Must be seen."
Ben Ennis, customer service assistant at the Guildhall, said: "When people say they've come from America we jokingly ask if they've come specially.
"But we are finding that lots of them are actually making a special trip to Leicester because of the discovery.
"It was lovely that our 50,000th visitor also came from out of the county."
