Sebastopol was the name of a large artillery mortar commissioned by the Ethiopian Emperor Tewodros II (1818–1868).

The mortar weighed approximately 6.7 tons, and was capable of firing off half-ton artillery rounds.

In an attempt to speed up industrialisation, Tewodros had welcomed British and French officials and a group of German missionaries into his kingdom.

[2] Although there are no records of the mortar being used in the battle it remains half-buried in the ground, on the plateau at Meqedela,[citation needed] near Amba Mariam.

A bronze replica has been cast and displayed in the centre of a roundabout at Tewodros Square, Churchill Avenue, Addis Ababa.
