The Chairir estate, which once belonged to one of the great princes of the Romanov dynasty, was built by the architect Krasnov. The august family visited Chaire more than once. In general, Nicholas II often visited the grand ducal estates, seeing some special need for this. As for Chair, perhaps the emperor even loved this place. When they took the sickly Tsarevich Alexei here, he felt better here than anywhere else. No one knew the obvious reason for the improvement in his condition. But everything was attributed to the special healing climate of the area. Maybe it was all about the Chair park, laid out on the estate of Grand Duke Nikolai Nikolaevich of the same name? This and many other secrets are revealed to readers by Valery Voronin’s novel “The Ancient Roots of Rus'. Scylla and Charybdis of Humanity" from the author's new historical series, which began with the novel "The Warrior's Castle."
