Question: Question: What year was the castle that served as the headquarters for the Okazaki Domain built? Passage:Okazaki-shuku was a part of the flourishing castle town surrounding Okazaki Castle, the headquarters for Okazaki Domain. The classic ukiyo-e print by Andō Hiroshige (Hōeidō edition) from 1831 to 1834 depicts a Yahagibashi, one of the few bridges permitted by the Tokugawa shogunate on the Tōkaidō, and one of the longest bridges built in Japan during the early Edo period. Okazaki Castle is depicted in the distance on the far shore of the river. Following the Meiji restoration, with the construction of railroads, the route of what became the Tokaido Main Line was laid down through the nearby village of Hane ( Hane-mura) to the south. Unlike Goyu-shuku and Akasaka-juku, but this did not cause a huge economic decline to Okazaki-shuku. There was a horse-drawn rail line connecting Okazaki to the train station, as well as a teachers' school, which kept the town alive. On the other hand, Okazaki was not able to compete with the growth of Toyohashi, which was located directly on the railway, and which gained city-status first. Because of fires during World War II and the subsequent rebuilding of Okazaki in the post-war years, there are few remnants of the post town remaining today.

Question: Question: In which country is the seaport city of Porto located where the wine received its name "port"? Passage:Port is produced from grapes grown and processed in the demarcated Douro region. The wine produced is then fortified by the addition of a neutral grape spirit known as aguardente to stop the fermentation, leaving residual sugar in the wine, and to boost the alcohol content. The fortification spirit is sometimes referred to as brandy but it bears little resemblance to commercial brandies. The wine is then stored and aged, often in barrels stored in a Lodge (meaning "cellar") as is the case in Vila Nova de Gaia, before being bottled. The wine received its name, "port", in the later half of the 17th century from the seaport city of Porto at the mouth of the Douro River, where much of the product was brought to market or for export to other countries in Europe. The Douro valley where port wine is produced was defined and established as a protected region, and the name Douro thus an official appellation, in 1756, making it the third oldest, after Chianti (1716) and Tokaj (1730).
