The main attraction on the Baltic coast is the historic city of St Petersburg, built on the banks of the River Neva and considered the most beautiful Russian city. The sea area between St Petersburg and Kronstadt, inside a man-made seawall, is a popular cruising area for Russian sailors.
These are the ATONS (Aids to Navigation) on which I can find no information. Three of them (photos 1, 3, and 5) are obviously the markers at the end of jetties. One is meant to keep the red on one side and the green on the other side in order to stay in the middle of the channel. In some countries the Red is on the right when you enter the channel and in some countries it is the green that is on the right. I have been unable to find out which way Russia does it.
The second photo looks like a cartoon of a lighthouse.
Equipment: Kronshtadt is a military port. It is prohibited to enter the port for vessels without a special permission.
Kronshtadt (often spelled Kronstadt) is the historic home port of Russia's Baltic Fleet. The city and naval base are built on Kotlin Island, located 30 km (19 mi) west of St. Petersburg.
The first lighthouse that I saw (and which I could identify) was the Kronstadt Rear Range Light which is in back of the main lighthouse in this series. It is the very tall (177 feet) lighthouse is an octagonal unpainted concrete tower with a red lantern and gallery located near the east end of the naval harbor at Kronstadt
Nearby located at the corner of a pier at the extreme southeastern tip of the Kronshtadt naval base, about 400 m (1/4 mi) southwest of the Kronshtadt lighthouse there are supposed to be two towers, quite close together, comprising a range and showing quick-flashing red lights. However, my photo shows only one tower, and it seems to be showing a white light.
Description: Active; focal plane 14 m (46 ft); white light, 2 s on, 2 s off. 12 m (39 ft) hexagonal cylindrical cast iron tower, painted red
