Syldavia is a fictional middle
European country featured in the
Tintin books. We see the most of this nation in the book
King Ottakar's Sceptre, in which
Tintin and his faithful
Snowy must stop a plot to overthrow the king of Syldavia and maneuver the country into accession to neighboring
Borduria. The later books
Destination Moon and
Explorers on the Moon involve an atomic research complex in Syldavia, at which
Professor Calculus designs an atomic rocket to go guess where.
The nation, whose capital is Klow, is also known as the Kingdom of the Black Pelican.
