Burning incense often means that divine blessing is spread or that a place is being sanctified.
There are entire streets for shoemakers and tailors, for grocers and beer sellers; there is a market place and there is a guildhall, and near the shore, where there was once an island, stands the splendid Church of St. Nicolaus. It has an immensely high tower and spire; how it is reflected in the clear water! Near this is Our Lady's Church, where Masses are sung, where incense gives out its fragrance and wax candles burn. The 'merchants' haven' is now the Bishop's town; the Bishop of Roskilde rules and reigns there.
