Earth Sandwich / City antipodes / Lagos

Antipode finder · Nigeria

The antipode of
Lagos.

Draw a straight line from Lagos (6.45° N, 3.39° E) through the centre of the Earth and it comes out at 6.45° S, 176.61° W, in the South Pacific Ocean, 302 km from the nearest dry land, off the coast of Kiribati. The other slice of an Earth sandwich would sink.

Two globes: one centred on Lagos, one centred on its antipode at 6.45° S, 176.61° W

Can you make an Earth sandwich from Lagos?

No, not from Lagos itself. The other slice would land in the South Pacific Ocean, 302 km from the nearest dry land (Kiribati), where the sea floor lies about 5,880 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 752 km from Lagos, 22 km from Tibiri, Niger. Its other slice would go down 9 km from Mata-Utu, Wallis and Futuna.

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.
