Earth Sandwich / City antipodes / Brazzaville

Antipode finder · Republic of the Congo

The antipode of
Brazzaville.

Draw a straight line from Brazzaville (4.27° S, 15.28° E) through the centre of the Earth and it comes out at 4.27° N, 164.72° W, in the North Pacific Ocean, 340 km from the nearest dry land, off the coast of the United States Minor Outlying Islands. The other slice of an Earth sandwich would sink.

Can you make an Earth sandwich from Brazzaville?

No, not from Brazzaville itself. The other slice would land in the North Pacific Ocean, 340 km from the nearest dry land (the United States Minor Outlying Islands), where the sea floor lies about 5,240 m below the surface. Boats do not count (Sandwich Law § 1.3).

The nearest place from which an exact Earth sandwich is possible is 851 km from Brazzaville, 202 km from Lodja, Democratic Republic of the Congo. Its other slice would go down 4 km from Banana, Kiribati.

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.
