Tanjung Kupang Memorial Park commemorates the 1977 crash of Malaysian Airline System Flight 653, one of Malaysia's major aviation tragedies. The memorial is simple, but it gives a specific human history to a part of Johor that most travellers otherwise pass without context.
It is a reflective stop rather than a broad attraction, and it sits away from Johor Bahru's usual city sights. Visit only if you have an interest in modern Malaysian history or are already travelling toward the western edge of the district.
