Showcasing both historical and contemporary architecture in the area, the Rotterdam Architecture City book was produced as a "compact and up-to-date architecture guide that enriches the visitor's experience".
The Dutch city is home to a growing number of inventive structures, including MVRDV's Markthal – a curved residential complex that arches 40 metres high over a marketplace. Find out more about the project in our interview with architect Winy Maas.
Also highlighted within the book is the city's Centraal Station, which was renovated in 2014 and now features an angular metal-clad canopy at the entrance, and OMA's colossal De Rotterdam skyscraper – watch architect Rem Koolhaas explain the project in our exclusive interview.
OMA's 1992 Kunsthal art gallery, which was upgraded by the firm after a robbery in 2012, is included with other city's and the 1931 Van Nelle Factory designed by architect Leendert van der Vlugta in the International Style – now a World Heritage Site.
Each building, garden and park featured within the publication is marked on a detailed map of the city, along with a list of art in public spaces.
Written by Paul Groenendijk and Piet Vollaard, with photography by Ossip van Duivenbode, Rotterdam Architecture City is available to buy for €19.95 (approximately £14) from the Nai010 website.
