Buildings thumb|The Johanniskirche (Johannischurch) thumb|Nordermarkt; also visible is Große Straße thumb|Harbour of Flensburg at dawn Flensburg has a well-preserved Old Town with many things to see from centuries past. Characteristic is the row along the waterfront. Three of the four old town cores are along this north–south axis. The building boom in imperial times led to a partial rebuilding of the Old Town, but without destroying its structure, and leading to notable expansion of the town. Virtually unscathed in the Second World War, Flensburg, like other places in Germany, adopted a policy of getting rid of old buildings and rebuilding in the style of the time. Lack of money limited this trend in Flensburg, but before the policy ended in the late 1970s, countless old buildings had been demolished in the north and east Old Town, to be replaced by newer structures. Despite great losses, Flensburg still has a compact, well-preserved Old Town in the valley with good additions to what was built in the founders' time on the surrounding heights.
