Yarmouth, Maine: Brinley Associates: 1983. Vuurtoreneiland  Vuurtoreneiland ("Lighthouse Island") is a small island in the IJmeer, Netherlands, just off the coast of Durgerdam. The island's main function is as a base for a lighthouse; a military fort on the island was abandoned in the 1930s. The island's lighthouse has been in operation since 1700; it is named for the opposite point on the mainland, "Hoek van 't IJ", or "Corner of the IJ". The first lighthouse was a square, stone building. In 1809, the island was equipped with a military post, which, in 1844, was expanded to a real fort, which, in 1883, became a part of the Stelling van Amsterdam. The lighthouse was replaced with a cast-iron construction in 1893, which is still standing. At the end of the nineteenth century, a bomb-proof building and artillery battery were built on the island, but its five guns were moved to Den Helder in 1904. In 1959, it was delisted as a stronghold, but the last soldiers had left long before. In 1981, the island was listed as a Rijksmonument, and in 1996, a bridge was built, which connected the island and the mainland. The fog signal was deactivated in 2001, and the light was extinguished in 2003, when the last lighthouse keeper retired. It was rekindled in 2005. The island is a UNESCO World Heritage Site. It is owned by the Dutch state, and is managed by Staatsbosbeheer. Since a few years, a restaurant is located on the island, with a daily ferry service from Amsterdam    LAK-17  The LAK-17 is a Lithuanian single-seat sailplane that was designed at the Lithuanian Aero Club ( or LAK), and is manufactured by Sportinė Aviacija.
