Fire destroyed nearly 60 percent of one of the world’s largest motorcycle museums, the National Motorcycle Museum near Birmingham, England, Tuesday.

According to a BBC report, three of five exhibition halls and approximately 650 of the 900 vintage motorcycles stored and displayed at the facility were damaged or destroyed. The report described the motorcycles kept at the museum as “unique, priceless and irreplaceable” and valued the loss between $11.2 and $14.4 million.

The cause of the fire is under investigation.

Museum owner Roy Richards told reporters that he will reopen the museum.
