The monument comprises the remains of limekilns, quarries and associated buildings. These are of nineteenth-century origin but continued in use into the twentieth century.

The Fladdabister limekilns are set on a prominent rocky knoll, into which quarries have been dug for limestone to burn. There are two kilns, each of similar design. They are circular on plan, about 7m across, with small lintelled draw-holes at the base. Remains of iron lintel supports survive above at least one draw-hole. The more westerly kiln has collapsed slightly on its SW side in recent years.

All around the kilns are large quarry pits, while to the SE, on the flanks of the mound and partly set into an old quarry, are the remains of two rectangular-plan buildings, the more westerly mortared, the other of drystone construction. The larger appear to have been partly of two-storey construction, and may have been associated with the operation of the quarries and kilns.

These are kilns which would have produced lime from local limestone for agricultural purposes and for construction, and operated until replaced by imported lime produced on an industrial scale.

The area to be scheduled consists of the whole of the quarried knoll, including the kilns on its summit and the buildings on its SE slope. It is irregular on plan, bounded on the NE by the top of coastal cliffs and on the S by the edge of a flat boggy area. It has maximum dimensions of 70m NW-SE by 55m, as marked in red on the accompanying map extract.

Statement of National Importance

The monument is of national importance as a fine example of a small-scale limestone extraction and processing complex, and illustrates the sophisticated utilisation of local resources practised prior to the ready availability of industrially-produced chemicals and of the means to purchase them. It is also of interest for its lateral perspective on Shetland's emergence from near-subsistence economy to its present role in international resource exploitation and trade.



RCAHMS records the monument as HU 43 SW 6, 9 and 10.

About Scheduled Monuments

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Scheduling is the process that identifies, designates and provides statutory protection for monuments and archaeological sites of national importance as set out in the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments that are found to be of national importance using the selection guidance published in Designation Policy and Selection Guidance (2019)

Scheduled monument records provide an indication of the national importance of the scheduled monument which has been identified by the description and map. The description and map (see ‘legal documents’ above) showing the scheduled area is the designation of the monument under the Ancient Monuments and Archaeological Areas Act 1979. The statement of national importance and additional information provided are supplementary and provided for general information purposes only. Historic Environment Scotland accepts no liability for any loss or damages arising from reliance on any inaccuracies within the statement of national importance or additional information. These records are not definitive historical or archaeological accounts or a complete description of the monument(s).

The format of scheduled monument records has changed over time. Earlier records will usually be brief. Some information will not have been recorded and the map will not be to current standards. Even if what is described and what is mapped has changed, the monument is still scheduled.

Scheduled monument consent is required to carry out certain work, including repairs, to scheduled monuments. Applications for scheduled monument consent are made to us. We are happy to discuss your proposals with you before you apply and we do not charge for advice or consent. More information about consent and how to apply for it can be found on our website at
