Lighthouses, water towers and windmills for sale: what converted landmarks really cost

Few buyers dream of an ordinary flat, but many dream of a lighthouse. Lighthouses, water towers, windmills and old towers look like the cheapest way to own a landmark, and reports about them appear in every country. We went through our country articles and collected what was actually published, with source and date where we have them. None of these properties is offered through us, most are asking prices rather than completed sales, and listings change fast. It is general information, not advice.

Lighthouses

Lighthouses are the most photographed and the most misleading category. In the United Kingdom, press coverage has described a Grade II listed former lighthouse at Paull on the Humber with a house attached at 189,950 pounds, and a lighthouse keeper's home near Wick in Caithness at offers over 85,000 pounds. Those listings are undated in the sources we saw and may be sold or withdrawn. A dated example sits at the other end: a Viewber roundup of 28 July 2026 says The Lighthouse in Croyde sold in 2024 for 5.25 million pounds after an original asking price of 7.5 million. See the United Kingdom.

In the United States, some lighthouses go to public bodies at no cost and others are auctioned through the General Services Administration. According to NPR in 2023, auction prices have ranged from 10,000 to 933,888 dollars. Older reports mention 159,000 dollars for the Superior Harbor Entry Light in Wisconsin and 71,010 dollars for a Lake Erie breakwall lighthouse in 2011. We found no 2026 results. See the USA.

In France, the Kerbel lighthouse at Riantec in Morbihan was bought at a state auction in 2003. Connexion France and Breizh-info reported in 2018 that it was listed at about 1.56 million euros, but a later piece says it has been rented out since 2003, so we do not assume it is on the market. See France. In Italy the state agency Agenzia del Demanio has offered disused lighthouses on concessions of 6 to 50 years (the 2015 tenders covered 11): you get the right to restore and use the building, not freehold. We could not confirm an open call in 2026. See Italy.

A cautionary tale from Estonia: the islet of Viirelaid, with a lighthouse built in 1882 and seven houses, was advertised in 2020 at 1,919,968 euros. Estonian World reported on 3 June 2020 that it was a publicity stunt and that most of the islet belongs to the state. See Estonia.

Water towers and windmills

Water towers are the genre that recurs in German classifieds and auctions. Berliner Kurier reported on 2 September 2026 a monument-protected eight-sided water tower in Guben, Brandenburg, listed at 370,000 euros with more than 5,000 square metres of land. The dpa agency reported on 1 September 2026 that the monument-protected Erlweinturm in Dresden was coming up at auction; we found no price. See Germany. In the UK, a disused water tower at Flockton near Wakefield was offered at auction with a guide price of 4,000 pounds, in an undated listing.

Windmills are mostly a Mediterranean story. In Greece we saw broker listings for a windmill of about 45 square metres in Parikia on Paros at 1.9 million euros (it already works as a cafe-bar, so the price reflects a business and a location), and a windmill-shaped house of 90 square metres on 26,500 square metres of land on Zakynthos at 350,000 euros, where the land is the main part of the value. They are asking prices and may be sold or repriced. See Greece. In Portugal, listings near Cascais and in the Algarve describe family homes built around a restored windmill tower; the agency pages are undated and we give no prices. See Portugal.

Towers, platforms and bunkers

Some lots are stranger still. Euronews reported on 4 and 5 June 2026 that a former East German demagnetisation station in the Greifswalder Bodden, built in the 1950s on about 600 piles, was sold at auction for 60,000 euros after 20 bids. The buyer gets a usage right, not land, and the structure can be reached only by boat. In Switzerland, press features say that the army has sold or closed many bunkers since the 1990s and that some were reused as a hotel or as data centres; we found no price. See Switzerland. In Georgia, Svan tower houses number in the thousands according to reports, but we found no sale prices and no confirmed rule on what heritage status lets you change. See Georgia. In Spain and Czechia we found no verified lighthouse or tower listings and describe none.

Why they are cheap, and why they are not

• Protection. Many of these buildings are listed monuments. Alterations need approval, and in Germany tax advisers say the monument tax relief applies only to work approved in advance by the monument authority.
• Obligations. In the US the buyer must maintain a lighthouse to historic-preservation standards, and the Coast Guard may keep an easement to service the navigation light.
• Tenure. Concessions and usage rights are not freehold, as the Italian and German examples show.
• Restoration. Europe 1 noted for French châteaux that restoration often costs two or three times the purchase price; the same logic applies to any building that needs a full conversion.
• Asking prices. The Croyde case shows how far an asking price can be from a sale price.

What this means for a normal buyer

• Treat a low price as a sign of work and restrictions, not of a bargain.
• Ask who owns the land, the access road and the shoreline before you ask about the building.
• Check whether you buy freehold, a concession or a usage right, and for how long.
• Get the monument or heritage rules in writing from the authority, not from the seller.
• Budget for survey, permits, utilities and insurance before the view.
• Do not rely on an old listing: many examples above are undated and may already be sold.
