Kotka lighthouse, Maritime navigation lighthouse in Loviisa, Finland.
The Kotka lighthouse is a navigation lighthouse near Loviisa on the Gulf of Finland. The tower displays distinctive horizontal yellow and blue stripes and stands as a key marker for ships traveling through these waters.
The lighthouse was built in the early 19th century as maritime trade expanded rapidly along the Finnish coast. It was constructed to meet growing shipping needs and to provide improved navigation support in the region.
The structure represents the architectural elements of Finnish lighthouse design, incorporating specific features developed for the challenging Baltic Sea conditions.
The light flashes four times every 30 seconds with a range of about 12 nautical miles to guide passing ships. The location allows visitors to observe the operation of an active navigation aid up close.
The structure uses a racon system that transmits the letter K signal, providing extra help during poor visibility. This electronic addition lets modern vessels identify the station even in difficult weather.
