The Old Fort and Constitution Hill are definitely worth a visit. The Fort is an Apartheid era prison museum worth the trip on its own. Immediately adjacent is the the amazingly beautiful Constitutional Court Building. An amazing experience that I still think about was a spur of the moment trip to the new Constitutional Court where our guide was Albie Sachs http://www.constitutionalcourt.org.z...iesachs/1.html ). A bit like a tour of the US Supreme Court with Thurgood Marshall as your guide. He does them about once a month on Saturday's. Book ahead. We got lucky and they let us join, partly because I with someone he knows. No booking required except for him.
