Background

Krudttårnet Gunpowder Tower, Frederikshavn

A 17th‑century gunpowder tower turned harbourfront museum, where naval history, bold engineering and Frederikshavn’s maritime story meet in one compact landmark.

4.3

Rising beside Frederikshavn’s harbour, Krudttårnet is a robust 17th‑century gunpowder tower that once guarded Denmark’s northern coastline. Built between 1686 and 1690 as part of the Fladstrand fortifications, this round Martello‑style tower later supported the Danish fleet during the Great Northern War and was dramatically moved 270 m in one piece in the 1970s to make way for shipyard expansion. Today it serves as a compact maritime and military museum with cannons, naval stories and summer events.

Local tips

  • Plan your visit in summer if you want to experience the Tordenskiold-themed historical town around the tower, when costumed interpreters and family activities bring the naval era to life.
  • Allow at least 30–60 minutes inside the tower to read the exhibits and examine the roof structure and cannons on the upper level; the site itself is small but historically dense.
  • Bring a light jacket, as the thick stone walls can keep the interior cool even on warm days, and the waterfront location can feel breezy outside.
  • Check current opening times and any event schedule in advance, as access to the interior and special activities may be seasonal or limited to specific days.
  • Combine a stop at Krudttårnet with a stroll along the harbour to photograph the contrast between the old defensive tower and modern ferries and shipyard structures.

Getting There

  • Train and walking from Aalborg

    Take a regional train from Aalborg to Frederikshavn Station; services typically run at least once an hour and the journey takes about 1–1.5 hours. A standard adult single ticket usually costs around 80–120 DKK, depending on time and fare type. From the station it is roughly a 15–25 minute walk through the town centre to the harbour area where Krudttårnet stands on Kragholmen. The walk is on mostly flat pavements but may include some cobbles and can be windy near the waterfront.

  • Car from Skagen and regional surroundings

    Driving from Skagen to Frederikshavn typically takes around 35–45 minutes via the main coastal route. There is usually public parking available close to the harbour and in central Frederikshavn, some of it time-limited or paid during the day with rates commonly in the range of 10–20 DKK per hour. From nearby parking areas you should expect a short walk over generally level ground to reach Krudttårnet, though exposed conditions by the water can make it feel colder in winter.

  • Local bus within Frederikshavn

    Local and regional buses connect residential districts and nearby towns to Frederikshavn’s central area, with journey times typically between 10 and 40 minutes depending on distance. A single adult ticket bought on board or via local ticketing apps generally costs around 20–40 DKK. Many services stop within walking distance of the harbour; from these stops, allow about 10–20 minutes on foot along urban streets to reach the tower, bearing in mind that wheelchair users may prefer routes with dropped kerbs and smoother surfaces.

  • Foot access from Frederikshavn ferry terminal

    If you arrive in Frederikshavn by ferry, for example from Gothenburg or nearby islands, you can walk from the ferry terminal to Krudttårnet in roughly 10–25 minutes, depending on the berth used and your pace. The route passes through an active port environment with some uneven surfaces and can be exposed to wind and rain, so suitable clothing and footwear are advisable. No additional transport costs apply, but allow extra time during busy ferry operations.

Seafront Stronghold of the Old Fladstrand

Krudttårnet stands like a stone sentinel on Kragholmen, a rounded tower that once formed the core of the coastal defences for the old trading settlement of Fladstrand, today’s Frederikshavn. Constructed between 1686 and 1690, it was designed to store gunpowder safely while withstanding bombardment from the sea. The thick masonry walls, small openings and compact footprint reflect a single, uncompromising purpose: to keep the harbour operational and the fleet supplied. Its strategic location at the entrance to the harbour meant that ships approaching the coast did so under the watchful eye of the tower and its associated batteries. From here, the Danish navy could control access to the Kattegat and the routes further north towards Norway. Even as the town around it changed from fishing outpost to industrial port, the rounded silhouette of Krudttårnet remained a constant landmark.

War, Fleet and a 4,500‑Ton Relocation

During the Scanian War and later the Great Northern War, Krudttårnet served as an important support point for the Danish fleet. Powder, shot and supplies were kept within its vaulted interior, ready to be distributed to the guns defending the harbour approaches. The building’s simple exterior concealed a highly functional military heart that helped secure one of Denmark’s key naval gateways. By the 1970s a new challenge appeared: the expansion of Frederikshavn’s shipyard. Instead of demolishing the old tower, engineers undertook a remarkable feat. The 4,500‑ton structure was braced with concrete rings, carefully jacked up and slowly pushed and pulled about 270 metres to a new position. Completed in 1975, this move preserved the historic building in its entirety and added a modern chapter of engineering ingenuity to its long story.

Inside the Powder Tower Museum

Today Krudttårnet functions as a small museum focused on naval warfare, local fortifications and the evolution of Frederikshavn as a harbour town. Stepping inside, you find exhibits of gunpowder barrels, cannonballs and weapons that evoke the thunder of past battles. Informative displays outline the tower’s role in coastal defence, its involvement with the fleet and the dramatic relocation of the building. On the upper level, the unique roof construction becomes visible, a sturdy timber framework designed to carry weight and withstand the elements. Here, cannons are displayed on what once served as the fighting deck, allowing you to imagine gunners loading and firing at hostile ships. From the embrasures, glimpses of the modern port create a striking contrast between centuries-old masonry and steel shipbuilding.

Tordenskiold’s Town and Living History

In summer the area around Krudttårnet often transforms into a historical townscape inspired by Tordenskiold, the famed Danish-Norwegian naval hero, and the period when Fladstrand played a role in his campaigns. Temporary wooden houses, stalls and tents appear near the tower, staffed by guides in historical costume who bring the 18th century to life through stories, demonstrations and playful activities. Family-friendly games, simple crafts and hands-on experiences give younger visitors an accessible way into the maritime history of the region. The tower itself is usually included in this living history environment, allowing you to combine a conventional museum visit with a more theatrical encounter with the past. Even outside event periods, the open apron around the tower offers clear views and ample space to appreciate its maritime setting.

A Compact Stop on the Frederikshavn Waterfront

Krudttårnet is a relatively small site, making it ideal for a short but rewarding stop on a wider exploration of Frederikshavn’s harbourfront. The surrounding open ground and views over docks and ferries highlight the town’s continuing role as a maritime hub. Information panels and the tower’s clean lines make it a straightforward place to understand: there is one main building, a focused story and a strong sense of place. Whether you come for a quick photo stop or linger inside the museum, the tower offers a tangible link between modern shipyards and centuries of naval history. Its survival and relocation testify to the value placed on heritage in an otherwise utilitarian port landscape, and its sturdy stone form continues to anchor the waterfront skyline.
