More than 2,700 stars are embedded into the pavement on the Hollywood Boulevard and Vine Street, in Los Angeles in the US.

Marilyn Monroe, Zac Efron, Scarlett Johansson, Ludacris and (just very recently) Batman are all part of the Walk of Fame. Thousands of tourists visit it daily, but there have been questions about who is and isn’t included and if this star-studded road is diverse enough.

BBC reporter Sam Granville speaks to us from the Walk of Fame and explains what it takes to get a star and whether it’s still regarded by celebrities as an important legacy.

An indigenous red-feather cloak was recently returned to Brazil from a museum in Denmark - where it had been on display for hundreds of years. There are other examples of historic and precious artefacts being returned to their countries of origin. And this is leading to a growing pressure to return more, like the Hoa Hakananai'a, originally taken from Rapa Nui (Easter Island).

The BBC’s Zeinab Dabaa in Cairo talks us through Egypt’s calls for the repatriation of three items: Queen Nefertiti’s bust, the Rosetta Stone and the Dendara Zodiac. Ashley Lime, a BBC journalist in Nairobi, explains the significance of the Benin Bronzes - and why some museums are reluctant to let them go.

Alongside the campaigns to get valuable and historic items returned, there are also efforts to digitise treasures. Chidi Nwaubani is the founder of Looty, a radical art collective which wants to use augmented reality to create digital versions of artefacts and, in their words, “loot back” treasures. He was speaking to BBC Click.
