Dozens of treasures from the collection of the Dutch royal family may be returned after an investigation found many were "wrongly obtained" during colonial wars.

Among them are a gold ankle bracelet given by a Balinese monarch in a bid to stop a Dutch invasion as well as weapons belonging to an Indonesian king.

The investigation was commissioned by the Dutch royals with Queen Maxima saying it would be published in full online as "transparency is a precondition for an open conversation with those from the countries of origin".

Almost 800 objects have already been returned from the collection in the last three years.

The number of works by Yayoi Kusama sold at auction in the past week for a total of $3,546,731, according to research by HENI News. The Japanese artist has consistently been one of the best-selling contemporary artists in recent years.

A rundown parking garage in a suburb of Paris is the last known location of the $102 million jewelry haul from the Louvre heist, according to a new book about the robbery.

None of the stolen jewels has been recovered despite the arrest of several subjects, but one of them - the diadem of Empress Eugenie - was captured on grainy security camera footage in a garage in the suburb of Aubervilliers.

According to an extract from the book published in Le Monde, two men are seen examining the object just under an hour after the theft but a police search of the premises 16 days later found nothing.

The book also highlights a series of failings that contributed to the robbery including the museum not having one individual responsible for security and a police patrol called by a witness speeding past the scene in the wrong direction as the four thieves drove off.

Louvre director Laurence des Cars eventually resigned months after the robbery to be replaced by Christophe Leribault.

Visitors to the Getty Center in Los Angeles will get a "more gracious and efficient entry experience" thanks to a new tram and renovated welcome hall.

The tram infrastructure is designed by architects Gehry Partners, the firm established by the late Frank Gehry, and will help transport the more than 1.4 million visitors the museum gets annually.

Tim Whalen, director of the Getty Conservation institute, said the renovation program would "strengthen the site’s sustainability and accessibility" and elevate "the quality, comfort, and depth of our visitors’ experience".

The center will close on March 15 next year while work goes on with reopening planned for spring 2028.
