The Cambodian Post office was built in 1890, then eventually restored and fully reopened in 2004. It fronts a small square on Street 13 — really Cambodian Post office is just a widening of the road — and is surrounded by other examples of colonial architecture in various states of upkeep. The post office is open 07:30 to 17:00, with a healthy two-hour lunch break from noon. Stamp collectors can make impulse purchases at the philatelic counter.
If you’re looking to get fit in Phnom Penh, there are a plethora of options — from aerobics at Olympic Stadium to the new public exercise equipment on the riverside. If you’re looking for something indoors and possibly air-conditioned, Phnom Penh has lots of gyms and fitness centres, some of which start at less than a dollar a day and many more that are surprisingly expensive.
