The first full summer of Hostačov's next chapter. From June through early September, the château becomes a landscape for retreats, residencies, gatherings, weddings, shared meals, quiet work, and temporary worlds.
Some periods are open. Some private. Some by application.
Hostačov is a 16th-century château in the Czech Highlands, ~70 minutes from Prague.
Across the season, people from unusually different domains keep finding themselves in the same rooms — researchers, technologists, artists, founders, contemplatives, facilitators, families, wanderers. Serious work alongside good company. Intellectual depth alongside embodied presence. Enough structure to hold things; enough openness for the unexpected.
What follows is the map of the season. A living document. The structure below will hold; details fill in over the coming weeks.

“This house shelters daydreaming, and the daydreaming, hopefully, in time shelters the house.”

Three weeks held lightly, around the territory where technology, philosophy, and complex systems thinking meet. Two halves, split by a company retreat (10–12 July) — the Human-Aligned AI Summer School in Prague (13–17 July) keeps a natural flow of people moving between them.
Come for a few days or the longer stretch. Quiet focused work, conversations that find their own shape, the château at an unhurried pace.
