Fine murals decorate the interior of the rock-hewn church of Yohannes Maequddi, a two-hour walk from Degum on a plateau of the Gheralta Mountains east of Debretsion. The access to the church is along a narrow cleft between glaring sandstone. There are two entrance doors, both in the Axumite-style of construction. The main entrance is for men while the secondary entrance to its right is for women. The spacious rectangular interior is best known for its ancient, well-preserved murals and paintings. Their style is quaintly primitive and is unique to this region.In the fastness of the Gheralta Mountains about thirty rock-hewn churches were built in early Christian times. In all, Tigray _ Ethiopia's northern-most region _ has more than 120 rock-hewn churches.
