I disagree this is a site for world heritage. It is already an INTANGIBLE site on the list and the rest of the place isn't what it was back in the day. Sacred sites are indeed on the WHS list and I wouldn't be surprised if it gets added but while the field may be sacred, the houses are traditional style and the performances are quite enjoyable, it's 85% intangible drumming and dancing. Also if you come alone they won't perform unless I pay a lot but worse is that it would feel strange to be the only guest, but they said I could wait for another group they expect later. Another hour later they did indeed show up and I only had to chip in for the total costs. The group also offered me to drive back on the Route 2 which saved me some bus journey time. I figure most tourists just do the trip from Bujumbura and I can see how it's a highlight of customs in Burundi you should put on your to-do list, just not as a tangible world heritage site.

In September 2019, I apparently commissioned Burundi's most famous drum site, the Gishora Drum Sanctuary, for an hourlong performance for an audience consisting of me and dozens of local children who saw me arriving, so decided to watch the show.
