A compulsory visit to Tuol Sleng and Cheoung Ek. Not a pleasant visit but a necessary one. The barbarism which so damaged Cambodia should not be forgotten.
On the way back I was shown the Russian Market which was a treasure trove of different stalls in an enclosed area. You could buy clothes and Buddhist statues and jewellery and watches and bike tyres and bike engines and food and casters and pottery.
In the evening did a sunset river cruise on the Mekong river. The price of $17 included transport there and a drink and fruit on the boat. Saw the 'rainbow bridge' which was lit up in the colours of the Cambodian flag. Happily it didn't tip down with rain as it might have done. Not as pretty as the Melaka river cruise but Phnom Penh is definitely more beautiful by night.
