A very rare nautical chart of the Gulf of Finland from Helsinki to St. Petersburg, Russia. This important chart was published shortly after the Finnish War of 1808 to 1809 between the Kingdom of Sweden and the Russian Empire which resulted in the creation of the Grand Duchy of Finland within the confines of the Russian Empire from the territory ceded by Sweden to Russia. The Gulf of Finland was, and remains, an important strategic artery for trade and defence for Russian, Finnish and Estonian interests that now include major oil harbours. The chart also includes four insets describing in greater detail the areas depicted. These include the inlet of the port city of Constadt located on Kotlin Island near St. Petersburg. The city of Constadt and its fortifications have since been designated as a World Heritage Site by UNESCO and was the main base for the Russian Baltic Fleet protecting the important Russian city of St. Petersburg. Other inset charts include those for the inlet of Wiborg, Revels Rehd, and finally the entrance to island of Utö, Finland. Other than the ubiquitous depth soundings and rhumb lines, the chart also includes fifteen drawings of important lighthouses to be found along the Gulf of Finland with notations such as locations and hight. The chart was published in Denmark by Johan Georg Blankensteiner, a renown Danish publisher of nautical charts, instrument maker and nautical suppler located in Copenhagen, Denmark.
This chart is exceedingly scarce and we have been able to identify but one other example, at the Bibliothèque Sainte Geneviève, Paris. Owned jointly by Geographicus and Vetus Carta.
