a sea in Europe between Denmark, Estonia, Finland, Latvia, Lithuania, Sweden, Germany, Poland, and Russia

For a beach holiday, I recommend the island of Gotland, which lies in the middle of the Baltic Sea. 如果想去海滩度假，我推荐哥特兰岛，它位于波罗的海中部。

This victory established Russia as a major European power, and gained a maritime exit on the Baltic, where Peter founded his new capital, Saint Petersburg. 这场胜利确立了俄罗斯作为欧洲大国的地位，并为其获得了波罗的海的海上出口，彼得在那里建立了他的新首都圣彼得堡。
