This paper presents the conservation and reassembly of the Tod Head lighthouse lantern in the storage area of the National Museums Scotland. The Tod Head lighthouse was located on the Scottish east coast, north of Edinburgh. The lantern was dismantled in 2011 and sent to the National Museums Collection Centre. Firstly we look at a technical explanation of a functioning lighthouse. The lighting device – which is called a lantern – uses Fresnel lenses, also called stepped lenses. The design of the lantern was a collaboration between the Scottish engineer David Alan Stevenson and the horologist Augustin Henry-Lepaute, partner of Augustin Fresnel. Secondly, a short history of the object is presented. Throughout the 20th century, the lantern has undergone many changes. The light has been electrified and the mechanism has been motorised. Finally we detail the conservation operations and the reassembly.

Tematem artykułu jest proces konserwacji latarni morskiej Tod Head przeprowadzony na terenie magazynu National Museums Scotland. Latarnia Tod Head znajdowała się na wschodnim wybrzeżu Szkocji, na północ od Edynburga. W 2011 r. rozebrano ją i wysłano do National Museums Collection Centre. Na początku sprawdzono dokumentację techniczną funkcjonującej latarni. Urządzenie oświetlające – które nazywa się latarnią – wykorzystuje soczewki Fresnela, zwane również soczewkami schodkowymi. Projekt latarni powstał dzięki współpracy szkockiego inżyniera Dawida Alana Stevensona oraz gnomologa Augustina Henry-Lepaute’a, współpracownika Augustina Fresnela. W pracy przedstawiono krótką historię obiektu. W XX w. latarnia przeszła wiele zmian. Źródło światła (latarni) zostało zelektryfikowane, a mechanizm (obrotowy) zautomatyzowany. W artykule szczegółowo opisano operacje konserwatorskie i ponowne złożenie obiektu.

In 2021, a functionally undetermined ring and a deformed upright of a Roman lantern were discovered with the help of a metal detector on the slope of the Hušák hill in the cadastral district of Lázy (district Svitavy). Both objects exhibit a similar metal composition. This is the second published find of a part of a Roman lantern from the territory of the Czech Republic and from the Barbaricum in general. The question remains whether the presence of a Roman lantern is related to the evidenced military intervention in the form of a Roman temporary military camp at the nearby town of Jevíčko, and whether the deposition on the slope of a prominent landmark was connected with ritual activities, or with metalworking, or with both.
