Although Port Elizabeth was never part of the actual war during the Anglo Boer War, there are a lot of Boer War related things around the city. This is where most of the British forces' horses and mules came through and both PE and Uitenhage had concentration camp sites. At some stage during the war the British received word of a possible Boer invasion and started setting up town defences. Part of these were a series of forts and trenches around the area. Four of these trenches are still visible just off the How Avenue parking area of Settlers Park.
