A somewhat crude replica of a Crossley Tender
Link on display at the Michael Collins Centre
Link between Clonakilty and Timoleague.
It stands on a bit of road built to simulate the point at Béal na Bláth
W4062 where Collins was killed. A few yards away is a replica of the armoured car which was also in the convoy.
At this centre you get a very detailed, step by step description of Collins' death. The Wikipedia article
Link on the same subject stresses the uncertainty that exists about the incident.
