Divle Obruk cave

Loading ratings…

A natural cave beneath a hill near Divle, Türkiye, is used to mature skin-packed tulum cheese. The district describes a cool, humid seasonal store; reported cave lengths differ between official sources.

A natural cave used as a seasonal cheese store

Divle Obruğu is a natural underground cavity used to mature Karaman Divle Obruğu Tulum Peyniri. The Ayrancı District Governorship places it under a hill about 1.5–2 kilometres southeast of Divle, also called Üçharman, and describes the passage as running east–west. The cave is a place-specific part of the cheese practice; it is not a cellar design that can be transferred to another site.

The local source describes the cave as a natural cold store and says a lift above the hill is used to lower and raise cheese. It reports an approximate depth of 36 metres. Its current page gives a length of about 150 metres, while a 2023 Karaman Agriculture Directorate report says about 250 metres. These differing published figures are not reconciled here.

A place, a seasonal environment

The Ayrancı source reports an interior temperature of about 4 ± 1 °C and relative humidity of 80 ± 5% during the cheese-storage period. It says the cave reaches about +22 °C in winter, when it is empty. These values describe the local source's account of this cave; they are not a universal specification for natural caves or a claim that temperature is actively controlled.

TÜRKPATENT identifies Karaman Divle Obruğu Tulum Peyniri as a registered designation of origin, registration number 270, dated 8 December 2017. The registered geography is Ayrancı District in Karaman Province. That product designation links the cave to a named regional cheese, while this build entry focuses on the fixed natural site.

Skin-packed cheese in the cave

The district's description says the cheese is packed into goat or lamb skin tulum sacks and matured in the cave for five to six months. Local and cultural-heritage accounts describe a seasonal cycle, with the mature bags taken out in autumn. The Türkiye Kültür Portalı records producer, weight, type and entry date on a cave slip and in the keeper's ledger, showing that the storage is organized by batch rather than treated as anonymous cave stock.

A 2016 Anadolu Ajansı photograph shows one interior view: skin-wrapped cheeses sit on wooden racks among rough cave walls. The rack arrangement belongs to that photographed scene; neither the district page nor the product register makes it a standard plan. The linked photo remains credited to AA/Mehmet Çetin, and the source does not state a reuse licence.

Use and historical limits

The Ayrancı District Governorship calls the practice centuries-old, but the sources used here do not provide a dated first attestation. The period is therefore recorded as unknown rather than assigning a medieval or earlier date. TÜRKPATENT's 2017 registration dates legal designation, not the cave's origin.

This page describes the natural cave, its documented use and reported local conditions. A full survey, geological account or guide to entering or building an underground space is not given.

History

The Ayrancı District Governorship describes cheese maturation at Divle Obruğu as a tradition lasting centuries, but the sources used here give no dated first attestation. This dates no particular cave feature.

Site

SettingNatural underground cave (obruk) beneath a hill about 1.5–2 km southeast of Divle/Üçharman village in Ayrancı District, Karaman Province, Türkiye. The district source describes it as extending broadly east–west; no complete survey is supplied here.
GroundNatural rock cavity; the sources used here do not establish a specific geological formation or provide a construction plan.
ClimateThe Ayrancı District Governorship reports about 4 ± 1 °C and 80 ± 5% relative humidity during the cheese-storage season; it says the cave reaches about +22 °C in winter when no product is stored. These are local source figures, not a universal cave-control target.
FootprintThe district page reports about 150 m length and 36 m depth; a 2023 Karaman Agriculture Directorate report gives 250 m length and the same approximate depth. The sources disagree on length, so this entry treats it as approximate and does not draw a scale plan.
NotesThis is a natural cave adapted for seasonal maturation, not a built cellar or a guide to excavation. The official local page describes a lift installed above the hill for lowering and raising cheese, but does not specify its design.

Structure and use

Materials

  • Natural rock cave — Natural underground space used in place as a cool seasonal maturation environment.
  • Wooden storage racks — Visible in a 2016 Anadolu Ajansı photograph of one cave-storage scene; the sources do not claim this is a universal arrangement.
  • Goat- or lamb-skin tulum sacks — Cheese is packed into prepared skins before the cave-maturation stage, according to the district source.
  1. The natural obruk is located beneath a hill southeast of Divle (Üçharman) village. The Ayrancı District Governorship says it runs roughly east–west. Its page gives approximate depth and length figures, while another official local report gives a different length; neither is a measured construction plan.
  2. Ayrancı's local description says the cave is used as a natural cold store for Karaman Divle Obruğu Tulum Peyniri. Cheese is prepared before cave storage and packed in goat or lamb skin bags. A 2016 Anadolu Ajansı photograph shows one storage scene with the skin-wrapped sacks on wooden racks; the photo documents one view, not a fixed layout for the whole cave.
  3. The district source reports a storage-season environment of about 4 ± 1 °C and 80 ± 5% relative humidity. It says the cave warms to about +22 °C in winter and is empty then. The reported conditions describe this specific place and season, not a setting that can be assumed for other caves.
  4. Local sources describe seasonal maturation lasting five to six months, with mature cheeses removed around October or November. TÜRKPATENT lists Karaman Divle Obruğu Tulum Peyniri as registered designation of origin No. 270, dated 8 December 2017; the district is the named production area.
  5. The cave is natural and its formation is not described as a human-built structure. The district says a lift above the hill is used to lower and raise the cheese. The sources do not establish the cave's complete interior plan or authorize a general excavation or entry procedure.
