Hákarl
A documentary account of Icelandic hákarl, fermented and dried Greenland shark. It describes cultural context and one production study, not a home preparation method.

Historical hákarl pits were covered gravel features near Iceland's coast; later production uses draining containers and a separate outdoor drying stage. Sources describe varied practice, not one standard plan.
The pit was one stage in a longer tradition
Hákarl is Greenland shark cured and dried in Iceland. A peer-reviewed review describes older accounts in which shark pieces were placed in gravel pits, often near the sea, then covered with stones, seaweed or turf. Seawater could reach some pits at high tide. The review presents these as historical practices; it does not document one surviving pit with a measured plan.
Jensen and colleagues note that the earliest written documentation of processed shark in Iceland dates to 1374. That is a date for the food practice, not proof that a particular pit or pit design existed then.
Containers and drying are separate stages
The same review distinguishes historical pits from later indoor perforated containers, which allow liquid to drain. Jensen and colleagues describe the traditional process as two stages, conditioning followed by drying, and report that contemporary producers use different methods. Their 2023 small-scale industrial study likewise separated fermentation from outdoor drying; its experimental setup should not be mistaken for a universal household design.
At Bjarnarhöfn in West Iceland, Visit Iceland describes a current museum and a drying house that visitors can see. This identifies a present-day place and drying stage, not a historic pit. The linked photograph shows hákarl hanging in a shed and is captioned accordingly.
What the sources leave open
The sources do not establish one standard pit shape, lining, depth, capacity or cover. Nor do they show that every producer used a coastal pit or followed the same sequence. The historic feature, modern perforated container and drying shed are related parts of a food tradition, but they are not interchangeable structures.
This page records historical evidence and current museum context; it is not a construction plan or a validated preservation procedure. The gallery photograph documents the later drying stage, while no image here claims to depict a historic pit.
History
Icelandic sources document hákarl production over a long period; Jensen et al. report the oldest documentation of processed shark in Iceland as 1374. That date is evidence for processed shark, not a date for the pit structure. Historical pit design and use are not independently dated here.
Site
SettingHistorical sources describe pits often near Iceland's coast. The present-day Bjarnarhöfn Shark Museum in West Iceland has a drying house; it is a contemporary example of the drying stage, not an identified historic pit site.
GroundA pit is described in broad terms as gravel or mud and covered with stones, seaweed or turf. No standard profile, dimensions or exact location is established.
NotesThe page separates historic pit descriptions from modern draining containers and drying sheds; the linked photograph shows drying meat, not a pit or perforated box.
A build is made where it stands: moving it means building it again.

Risks and precautions
Historical description only; this is not a construction guide or a validated food-safety process. Fresh Greenland shark can be unsafe to eat; follow current food-safety guidance and use properly controlled commercial products.
Materials
- Gravel or mud — Historical review describes pits near the sea; specific substrate varied or is not detailed.
- Stones, seaweed or turf — Reported as alternative pit covers in historical accounts.
- Perforated containers and drying shed — Modern separate stages described in production research; the 2023 study used wooden boxes and half-open wooden sheds.
- Historical descriptions report a gravel pit near the coast, covered with stones, seaweed or turf; this is a broad account, not a dated or measured example.
- Later accounts describe indoor perforated containers that let liquid drain, distinct from the older pit form.
- After conditioning, shark pieces are dried outdoors in a hjallur or drying shed. This hanging stage is separate from the pit or container.

The vessel and the ferment: pots, vats, skins and pits
Jars, barrels, skins, leaves, pits and whole rooms decide much of what happens to fermented and cured food. This is how a container works on its contents, and how people in different places chose theirs.
