Owing to that direction to the most mysterious and ancient structures of the Earth, located around St. Petersburg according to the angles of regular geometric shapes, we will be able to estimate these directions with an accuracy up to a degree if we come out to Palace Square. And without any tools and measuring systems.

In the article "Geodesy of St. Petersburg." it is mentioned that the Palace Square has a very precise orientation to the mysterious megalithic structures on Ponape island in the Pacific Ocean - Nan Madol, which azimuth in St. Petersburg is 53 degrees.

Therefore turns of regular geometric shapes on a certain number of degrees from the north-south axis will give the exact direction to Nan Madol.

For example, turning hexagram on 7degree counterclockwise, we obtain its orientation to Nan Madol, which coincides with the orientation of Winter Palace and the lines on the Palace Square.

Due to the fact that in St. Petersburg azimuth of Nan Madol interacts with the directions to the others historical objects according to the angles of regular geometric shapes, superimposing them on each other in the correct order, we can determine the desirable direction.

For this we need drawn on paper or cardboard hexagram, pentagram, octagon and nonagon which can be constructed with a caliper and a ruler.

First, define the direction to Teotihuacan. To do this superpose one of nonagon axes with the line on Palace Square.

Now count out counter- clockwise 5 divisions or 100 degrees. This line will be direction to Mexican pyramids with error 0.11degree.

Now superpose one of pentagram axes with the line on the Palace Square.

In this position we get the direction to the Tiwanaku and the Great Zimbabwe, which are perpendicular to each other, as well as the azimuths of Kailash and Mohenjo-Daro.

Next, superpose one of pentagram axes with the known direction to Teotihuacan, we will get the direction to Stonehenge and Angkor, as well as Baalbek and Lalibela, which, together with St. Petersburg lie on the same line.

САНКТ-ПЕТЕРБУРГ. ГЕКСАГРАММА. НОНАГОН. ОКТАГОН.

Now superpose diagonal of octagon with the line on the Palace Square, i.e. with the direction to Nan Madol.

In this position octagon determines the direction to Mecca and again to check for Angkor.

For determination of the direction to the Great Pyramid of Giza superpose octagon diagonal with the famous direction to the Teotihuacan and count out counter-clockwise 3 times by 45 degrees.

Then superpose already known direction to Mecca with the axis of the pentagram. In this position, we obtain the direction to the island of Vera and the Vatican - Rome.
