à  olta (; ; ) is an island in Croatia. It is situated in the Adriatic Sea in the central Dalmatian archipelago.
à  olta is located west of the island of BraÃÂ, south of Split (separated by Split Channel) and east of the Drvenik islands, Drvenik Mali and Drvenik Veli (separated by the à  olta Channel). Its area is .
In the 2011 census, the municipality of à  olta had a total population of 1,700, in the following settlements:
The highest peak of à  olta is the summit Vela Straà ¾a which is 236 metres high. On the north-eastern coast of the island there are the large bays of Rogaàand NeÃÂujam. In the western part of the interior of à  olta there is a field approximately long and wide.
The economy of the island is based on vineyards, olives, fruit, fishing and tourism. While the main settlements (Grohote, Gornje Selo, Srednje Selo, Donje Selo) are inland, the main fishing centres are Maslinica, which is exposed to only north-westerly winds, making it a good shelter for smaller boats. RogaÃÂ is the main port and NeÃÂujam the centre of the island's tourism.
Viticulture exists on the island since antiquity. The most famous autochthonous red wine variety is the DobriÃÂiÃÂ. According to DNA analysis, this variety is one of the original varieties of the American Zinfandel along with the Kaà ¡telanski from the Split area. The American wine pioneer Mike Grgich from Croatia brought the varieties to California. The Split noble family of the father of Croatian literature, Marko Marulià(1450-1524), who also lived on à  olta, were among the first to cultivate the DobriÃÂic intensively. In the 19th century viticulture in à  olta suffered severe setbacks. A trade agreement between Austria and Hungary with Italy allowed low-cost Italian wines to be imported duty-free. Diseases such as downy mildew and phylloxera reduced the stocks. The best qualities of national importance were created in the 1870s and 80s by Pietro degli Alberti from Porto Oliveto di Solta (Maslinica). At the Vienna World Fair in 1873 he received an honorary prize. At the Triester exhibition in 1882 he received a gold medal. Even in the interwar period there was intensive viticulture. As a result of the Titoism command economy, there is still no large wine industry upon the island. The cultivation is almost only for the own use. Some smaller winemakers, e.g. in Donje Selo, sell wine directly. It is also available at the market in Grohote. A large vineyard (on state leasehold land) was laid out for the first time again around 2015 on a hill on the road to Maslinica.
During the time of the Austro-Hungarian Empire the villages still have their Italian names. Villa Grohote, Villa Inf. short for Villa Inferior (Donje Selo) with the harbor Porto Olivetto (Maslinica), Villa Media (Srednje Selo) and Villa Superior (Gornje Selo) with the harbor Stomosca (Stomorska). The property tax structure of the Austrian-Hungarian administration was based on "Fractionen". The local parish of à  olta was divided into the cadastral community Grohote, Donje-Selo, Gornje-Selo and Srednje-Selo, i.e. under the Croatian place names. However, à  olta was no longer fully recorded in the land register by the Austrian administration. For parts of the island there is only the cadastre, i.e. site plans of the real estate, in which ownership and usage rights are not directly registered. This makes real estate transactions sometimes difficult.
The Telegraph arrived late at à  olta. In 1874, the k.k. State telegraph station Grohote handed over to the operation at "limited daily services". That was at the same time as in other smaller places of the monarchy as for example in the Carinthian Sankt Paul im Lavanttal or in Pontafel Pontafel.
In April 1941, Ã Â olta came under Axis occupation, first by Italy. Nazi Germany took over after the September 1943 Armistice. In March and April 1944, Ã Â olta was the site of two British-American commando raids ten days apart which took many Nazi prisoners and destroyed numerous installations.
