150 years ago, the prime meridian on the Russian maps went through Pulkovo. And there used to be an observatory in our country – it was housed by the Kunstkamera tower on Vasilyevsky Island, Saint Petersburg. But the city was growing rapidly, and it was becoming more and more difficult to make observations there. The observatory was then moved to a new place near the village of Pulkovo in the Pulkovo Heights. Vasily Yakovlevich Struve, a newly appointed director, went abroad and ordered the first-rate equipment. After looking through the telescope at the Pulkovo Observatory, the poet Alexander Blok even saw an angel but in truth, it was a weathercock of the Peter and Paul Cathedral.
