Villa Petrolea is today a spacious mansion housing the Nobel Brothers’ Museum and the Nobel Oil Club. It was completed in 1884 and served as the Nobels’ residence in Baku until 1924. In between those years the Nobles played a major role in exploration, extraction and transportation of oil from the Baku region. Ludwig formed a stock company in 1879 in which the Nobels were the main shareholders. The company gained a 15% share in the oil products of Azerbaijan in this period. The Nobels built the world’s first tanker in 1878 and called it the Zoroaster. A picture of this tanker now adorned a wall in Villa Petrolea.
