A decade after the genocide that left more than 800,000 dead, Rwanda is building memorial centers. “Ten years on, Rwanda is erecting its first proper memorials – and racing to complete them by April 7, the anniversary of the first day of slaughter, when centres will open their doors to survivors, perpetrators, scholars and tourists. For those who have kept guard over mass grave sites lest the remains – proof of the genocide – disappear, these centres offer a chance to end their vigil and rebuild their lives.”
