No, you cannot buy tickets on site for New Ameland Square, as it is a public square with no entrance fee. No tickets are required for access.
New Ameland Square is a public space and not a commercial attraction that requires tickets for entry. Therefore, there is no ticket booth or any facility on site to purchase tickets.
Access to the square is completely free and unrestricted. Visitors can simply walk into and around the square at any time, without any prior booking or payment. This policy aligns with its function as a central communal area for the village of Nes.
Any purchases made around the square, such as food or drinks, are direct transactions with individual businesses and are separate from accessing the square itself. Therefore, the concept of buying tickets does not apply to Nieuw Ameland Plein.
