Post Symposium Tour 11th – 14th September  -  “Mills in the Danish-German borderland”

The post-Symposium tour brought us to southern Jutland – once a duchy under the Danish king, from 1864 it was under German rule, and then once again united with Denmark in 1920. This history has, of course, influenced the development of the mills. On one day we visited Mandø in the Danish Wadden Sea. Mandø is an island which is reachable only during low tide. The island has only 62 inhabitants, but they have one of the smallest windmills in Denmark with machinery for making pearl barley. As a contrast we also visited the highest Danish windmill which is in Højer.

Mariendalsmøllen: In 1757-60 a windmill was built at the outskirts of Aalborg as supplement for 3 watermills in the city. In 1893 it was replaced by a bigger and more modern Dutch windmill. The mill contains millwork, gears etc., but unfortunately it is only used as a landmark.

Øster Sundby windmill: Moved from Ravnstrup to the present place in 1910, after the old mill burned down. Dutch mill with original springsails. In daily use until 1967.

Vodskov windmill was first built in 1882. It burned down in 1910, and was replaced by the present mill, which was moved from Flamsted. Despite the mill’s small size it has a lot of machinery (the owner was a millwright).

Dorf water- and windmill: The watermill is first mentioned in the 17th century. In 1877 the windmill was build as supplement in times of drought or frost. About 1920 the waterwheel was replaced by a Francis turbine, and the watermill was turned into a power plant that supplied the farm with electricity.

Godthåb hammer mill: Originally a paper mill, which in 1858 was rebuilt as a hammer mill. In 1868 the Poncelet waterwheel was replaced by a Francis turbine. The waterwheel is exhibited outside the mill. Inside is a rich maschinery, which is still working now and then.

Hjerritsdal watermill: First mentioned in the 15th century. In its present shape it is from 1832. It has an interior overshot waterwheel and under drive (the spurwheel beneath the stones), which is typical for North Jutland. It is situated in a marvellous landscape.

Havnø windmill: Small Dutch mill built in 1842 with the original machinery for grinding rye and pearled barley. In the 19th century it produced pearled barley for export to Norway.

The exhibition: Danish Millwrighting through the ages at Nordjyllands Historiske Museum, Hadsund. An exhibition arranged by curator Lise Andersen.

Møllebygger John Jensen Aps, millwright workshop. The workshop was founded 1882. From 1978 till his death in 2008, the owner was the well known Danish millwright John Jensen. His son Michael Jensen continues his father’s work.

Tadre watermill: First mentioned in 1405. In its present shape it is built about 1840. It has an overshot waterwheel and over drive (spurwheel over the stones), which is typical for Seeland.

Ringsted windmill: Excellent Dutch windmill from 1872, with a very rich machinery. It was in daily use until 1965. Fully restored in 1886. Today they produce organic flour.

Lille Mølle: Watermill with two overshot wheels. The mill was once owned by the molinologist Anders Jespersen, who made a lot of molinological experiments with his Lille Mølle (the name means Little Mill).

Ulbølle windmill is built 1863 as a brick laid windmill with reefing stage. One of only 3 Danish mills with iron sails stocks. Remark the yellow color of the sails stocks, which is typical for southern Fyn. . In daily use until 1970.

Rødkilde watermill once was a hair powder mill, built in 1754. Later rebuild for grinding cereals. It has the biggest overshot wheel in Denmark (5,65 m). In 1994 it was restored by millwright John Jensen. The restoration was given the Europa Nostra award for well executed restoration and handicraft.

Grubbe Mill (water- and windmill). The watermill is first mentioned in 1599 but has been rebuilt many times. The windmill was moved from Nykøbing on Seeland in 1892. The windmill was seriously damaged in a gale in 1999, but is fully restored.

Kaleko watermillis the oldest preserved watermill in Denmark. It is probably from the time of king Valdemar Atterdags (1340-1375). Originally it had undershot wheels, but in the 17th century it got 2 overshot wheels. The mill was opened as museum in 1917.

Ventepose watermill is one of Denmark’s three oldest watermills, built in the 17th century. It was in use until 1934. Built on the shore of the island Tåsinge. The farmers came by boat with their corn.

The Symposium took place from the 17th to 25th of August 2019. The theme of the Symposium was “Mills in history and archaeology”.

MapIn addition there was the opportunity to participate in a 4-5 days pre-tour to the south-east of Germany (Saxony), as well as in a 7 days post-tour to the middle of Germany (Hannover). 
As part of the Symposium a visit was organized to the mills in Berlin and Brandenburg and to important museums at Berlin.

The venue of the Symposium

In 2019 the Symposium took place in the city-centre of Berlin.
The paper sessions and presentations were held in the conference centre of the hotel.

Call for Papers

We called on all TIMS members and others (*1) to present their molinological research as a formal paper and/or as an informal, short contribution. Papers on all molinological topics were welcome.

Our theme was:  “Mills in history and archaeology”, so papers on this topic were appreciated.

The deadline for submission was the 1st of April 2019.  Please read and follow the “Formal Paper instructions”, which can be found here.

Formal papers

The symposium participants got the possibility to download the papers in advance and were expected to have read the papers; therefore, authors received only 20 minutes for presenting a summary of their paper and 10 minutes for engaging in discussion with the audience.

Key presentation/papers

UraniaAt the Berlin2019 Symposium wehaf an “Open to the public presentation day” with 5 key speakers giving a presentation to large audience (200 +).  On our first day of the Symposium, 18th Aug. 2019, we used the URANIA (*2)  for one day “Public day of Molinology”. These presentations aimed to attract large audience from all over Germany, to make contact to existing and new members and to make the public aware of how important it is to save mills of any kind as significant technical/historical monuments.

This event was sponsored by various mill organisations.




Informal Presentations

For informal contributions we expected in advance detailed information (paper or presentation file) on the subject. The time required to present the informal paper: maximum 20 minutes including discussion. Deadline for submission was the 1st April 2019.





More than 40 years had past since TIMS last visited Denmark for the Second Symposium in 1969, and we were happy to invite our members to come once more to – not just the native country of the vikings and the fairy-tale writer Hans Christian  Andersen – but also that of Poul la Cour and Anders Jespersen.

The Denmark Rødkilde Fyn 13th Symposium took place in Aalborg, Denmark, from the evening of Saturday the 3rd September to Sunday the 11th September, 2011. We offered a varied program of lectures and visits to mills, comfortable conference facilities connected to the hotel and a partner program with sponcered admission to museums, free guided tour of old Aalborg and a bustrip to Skagen, the northern point of Denmark where to seas meet.

Aalborg is easy to reach whether you arrive by train, bus or plane, and the conference center is situated close the old town center.

Together with the IM all members received a “call for papers”, but we indicated that we particularly would appreciate contributions on the subject “the correct preservation of mills”, as we hoped to have a prolific discussion about the principles and the practice of preservation.

One day was reserved for presentations from invited guests who lectured on the subject “Foreign Influences on Danish millwrighting”. The construction of mills in Denmark since the middle ages had been strongly influenced by developments from other European countries, firstly from medieval England, then the renaissance HDK2010 logoolland, Friesland and Holstein, and in the later years again from England, Germany, France and USA.

We offered pre-tour to the paradise of mills, Bornholm and Skåne (in southern Sweden), with departure from Copenhagen on 30th August, and post-tour to Southern Denmark. The post-tour finished in Copenhagen 14th September, 2011.

We tried to offer a number of places at a reduced price, which would be granted after application from students, and members from soft-currency countries under the condition that the applicant contributed a paper to the Symposium.

The logo for the Symposium was drawn by Mogens Pedersen, Denmark, and is inspired by a papercut  made by the fairy tale writer Hans Christian Andersen.
