This led to the construction of the shopping mall Hoog Catharijne (nl), music centre Vredenburg (Hertzberger, 1979), and conversion of part of the ancient canal structure into a highway (Catherijnebaan). Protest against further modernisation of the city centre followed even before the last buildings were finalised. In the early 21st century the whole area is being redeveloped.
