The only "must see" I heard about was this, and I reckon for good reason. Those lamps are actually gas-powered still, requiring the services of a lamp-lighter with a cape and everything (I'm 70% sure I caught the smallest glimpse of him once), apparently one of only two cities in Europe still doing it. As you can see, the vibes (especially in overcast weather during Christmas) were extremely on point. ⛪️🏝️🕯️
