Schoolchildren Alexandra and IVAs come to visit their grandmother in Dobromil for the summer holidays. The town welcomes them with the funnel River, the Old Town Hall, the Arsenal Museum and a maelstrom of exciting adventures. Together with Uncle Grits, they explore the secrets of the city, bring back to life the stopped clock of the Town Hall, learn the amazing history of the city, which has an apple with swords stuck on its coat of arms.

This book is not a textbook or a boring lecture. Trips to the Dobromil Region, simple dialogues and short stories will introduce readers to historical sites and related events. The prototypes of the heroes – Grits, Mr. Professor, Mr. philanthropist, Mr. photographer, Mrs. teacher and others – are easily recognizable: they live among us.

The book is intended for readers of primary and secondary school age.
