Today, the church is home to a Baptist congregation, but its list of former operators includes a far more sinister name – the KGB. During the Soviet times the church's spire was fitted with powerful radio and surveillance equipment. It was the highest point in Tallinn after all, and the Viru hotel was already too wired.
If it's a good view you're after, you'll be happy to know you can climb the church's spire, which offers a 360-degree view of Tallinn. You'll have to pay a small admission fee, but the view is worth it. Did you know that the St. Olaf's church used to be the tallest building in the world (though only for 76 years) 'til the Eiffel Tower was built.
We've ensured we keep the nice silhouette of Tallinn by law - no building in Tallinn can be built higher than St Olaf's Church.
