Up 240 steps, behind a padlocked wooden door, is a shrine holy to both Christian and Muslim believers.

It is not well known. Wary of flocks of tourists, the people in Makedonski Brod, in south-western Macedonia, have kept its existence a well-guarded secret for years.

The aged building, marked only by a cross from outside, is decorated within by Christian icons, and portraits of both Jesus Christ and Muslim saints.
