Is there free entry to all parts of Open Delft Museum?

Quick answer

The open-air aspects, like walking streets and canals, are free. However, entry to specific indoor attractions like the Nieuwe Kerk tower or Prinsenhof Museum requires a fee.

The inherent 'open-air' nature of `Open Delft Museum` means that exploring the city's streets, canals, squares, and general atmosphere is entirely free of charge. You can walk, cycle, and immerse yourself in the historical environment without paying an entrance fee to the 'museum' itself. However, many significant historical points of interest are housed within buildings which _do_ charge an entry fee. Examples include climbing the Nieuwe Kerk tower, visiting the Oude Kerk interior, or entering the Prinsenhof Museum. Planning which indoor attractions you wish to visit will help you budget your trip.
