Phraseologism “At Charlemagne” means “at the fence of the Summer Garden from the side of the Mikhailovsky Castle.” This fence was created according to the drawing of the architect Ludwig Ivanovich Charlemagne, from whose works the famous building of the Alexander Lyceum on Kamennoostrovsky Prospekt, the Tea House pavilion in the Summer Garden, the building of the fire department and the Ministerial cottage on Kamenny Island have survived to this day.

However, the most famous work of the architect turned out to be a lattice that forms the southern border of the Summer Garden. It is not as majestic as Yu. M. Felten’s fence, but among St. Petersburg residents it is no less loved. The fence consists of alternating links, decorated with the image of the head of the Gorgon Medusa. In the center of the fence is the entrance to the Summer Garden from the Moika River.

Petersburgers, making an appointment at the southern entrance to the Summer Garden, say: “Let’s meet at Charlemagne”, which is why this wording does not require any additional clarifications.
