Kosmonosy

Kosmonosy is a small town in the Czech Republic, located in the Central Bohemian Region within the Mladá Boleslav District. It sits in the Jičín Uplands and forms a conurbation with the larger and better-known city of Mladá Boleslav. While Kosmonosy rarely appears on tourist maps in its own right, its immediate proximity to a much bigger urban centre makes it a natural stop for anyone exploring the wider area.

How many people live in Kosmonosy?

The town currently has about 5,400 inhabitants. For comparison, at the end of 2003 Kosmonosy had just under 4,900 residents, and the town's area at that time measured 1,140 hectares. These figures show that despite its modest size, Kosmonosy has grown steadily in population over the past two decades.

Where exactly is Kosmonosy located?

The town lies in the Central Bohemian Region, within the Mladá Boleslav District — an area closely associated with the Czech Republic's automotive industry. Kosmonosy borders directly on the city of Mladá Boleslav, and together the two form a single built-up urban area where the administrative boundary is barely noticeable on the ground. Geographically, the town belongs to the Jičín Uplands, a hilly landscape typical of the northern part of Central Bohemia.

What is Kosmonosy known for?

The town's most recognisable feature is its psychiatric hospital. This institution is the main reason Kosmonosy's name is known across the Czech Republic — more for its role in mental healthcare than for any historic landmarks or scenic attractions. For visitors interested in the history of healthcare in the region, it offers a point of reference when touring the area around Mladá Boleslav.

Is Kosmonosy worth visiting alongside the rest of the region?

Given its direct border with Mladá Boleslav — best known as the home of the Škoda car factory — Kosmonosy can serve as a natural addition to a visit to this part of Central Bohemia. The hilly terrain of the Jičín Uplands is well suited to short walks and countryside outings, and the town's closeness to a larger city means easy access to accommodation, dining and transport connections.
