Around 1627, the three canals were connected with the Tijgersgracht canal. The new canal was lined with coconut trees; according to a contemporary observer, "Among the Grachts, the Tygersgracht is the most stately and most pleasant, both for the goodliness of its buildings, and the ornamentation of its streets, which afford a very agreeable shadow to those who pass along the street". The Prinsestraat, originally the street leading to the Castle, became an urban center connecting the Castle's south gate with the city hall.
