Chapter Deanery, Baroque deanery in Hradčany district, Prague Castle complex, Czech Republic.

The Chapter Deanery is a Baroque building within the Prague Castle grounds, featuring curved lines and stone ornaments typical of the style. The structure has multiple stories with spacious rooms that once housed senior clergy members.

The core of the building retains Romanesque and Gothic construction, but its present form comes from a High Baroque rebuilding carried out in 1705–1706 for chapter dean Adam Ignác Mladota ze Solopysk, to a design by Jan Blažej Santini-Aichel. The result is also called Mladota's House.

The building is also called Mladotův dům (Mladota's House) after Adam Ignác Mladota ze Solopysk, the chapter dean who had it rebuilt in 1705–1706. In the pediment, three coats of arms in cartouches stand side by side: those of the metropolitan chapter, the deanery of St. Apollinaris and Dean Mladota himself.

The building is part of the castle grounds and can be reached through the main entrance to the complex. Visitor access may vary depending on seasonal openings and special events hosted on the premises.

The facade's central pediment holds three coats of arms in rich cartouches: those of the metropolitan chapter, the deanery of St. Apollinaris and Dean Mladota. The window cornices of the piano nobile alternate triangular and segmental shapes in an ABBABBA rhythm, a detail easily missed from the courtyard.
