Russian anti-aircraft gun on Phu Si

One of the more interesting and perhaps one of the oddest things you will come across while you are visiting Luang Prabang is an anti-aircraft gun on top of Phu Si. 

Located on a crest on the southeastern side of the summit, this Russian anti-aircraft gun was most likely lugged up Phu Si during the Second Indochina War; either that or it was brought in by helicopter. 

It is definitely worth checking out either on your way up to the summit or on you way back down. You can get on it and give it a spin for a makeshift merry-go-round ride.
