What it commemorates
The Win-Win Memorial was inaugurated in December 2018 to mark twenty years since the end of the Cambodian civil war. It commemorates the so-called win-win policy, under which remaining Khmer Rouge commanders and fighters were offered amnesty, retention of rank and reintegration rather than prosecution, in exchange for defection.
The last strongholds fell in 1998, and the conflict that had run in one form or another since 1970 came to a close. The monument presents this as the decisive act of national reconciliation.
The site
The memorial stands on the Chroy Changvar peninsula, across the water from central Phnom Penh, in landscaped grounds beside the river. Its architecture borrows deliberately from Angkorian forms, and reliefs around the base depict the reunification and the return of fighters to civilian life.
It is a large, formal, state-built monument and it reads as one. Visitors interested in how modern Cambodia narrates its own recent history will find it more revealing than visitors looking for an aesthetic experience.
Visiting
Chroy Changvar is a short drive from the centre across the bridge, and the grounds are free to enter and open during daylight. It combines naturally with the riverside walk on the peninsula, which has become a popular evening spot for Phnom Penh families.
For context, pair it with Tuol Sleng and Choeung Ek — those sites cover what happened, and this one covers how it ended. Reading about the amnesty debate beforehand is worthwhile; it remains contested, and the memorial presents one side of it.
