Centre point

The centre point of Wales is dependent on whether only the mainland is used for calculation or outlying islands as well.

One centre point is calculated to be near Cwmystwyth, Devil's Bridge, Ceredigion (52°19′48.791″N 3°45′59.072″W; grid reference SN7972871704)[1]

Many points are on, or near sea level, but due to high rainfall, there are no natural dry pieces of land below sea level - see rivers and lakes below.
