In this church I preached my first sermon. The history of this picturesque church in Prague goes all the way back to 1178. As you can see even from this small picture, it is a unique and bizarre structure, over centuries it was rebuilt many times and in many different styles - Romanesque, Gothic, Renaissance and Baroque. Throughout its long history it was a parish church, a seat of radical Reformation, it was deconsecrated and turned into a warehouse and apartment building with some stores, before it was reconstructed and made into a Protestant church for university students. But for most of its history this church was part of the Prague city wall - hence its name St. Martin in the Wall. The south wall of the church was integrated into the fortification of the Old Town of Prague. Although the church wall was hardly thicker than the rest of the city wall, it was, nevertheless, its safest part. Noone would ever dare to attack the city through the church or even enter the church armed and in hostility! This historic little church is in fact an embodiment of the very old and revered concept of sanctuary. In Lent this year we will talk, learn and celebrate sanctuaries - these important sacred spaces. Why we need them, how we can use them and why we must protect them.
