Earth Sandwich / City antipodes / Birmingham

Antipode finder · United Kingdom

The antipode of
Birmingham.

Draw a straight line from Birmingham (52.48° N, 1.90° W) through the centre of the Earth and it comes out at 52.48° S, 178.10° E, in the South Pacific Ocean, 312 km from the nearest dry land, off the coast of New Zealand. The other slice of an Earth sandwich would sink.

Two globes: one centred on Birmingham, one centred on its antipode at 52.48° S, 178.10° E

Can you make an Earth sandwich from Birmingham?

No, not from Birmingham itself. The other slice would land in the South Pacific Ocean, 312 km from the nearest dry land (New Zealand), where the sea floor lies about 4,920 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 314 km from Birmingham, 8 km from Réville, France. Its other slice would go down 731 km from Waitangi, New Zealand.

How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
