This is the 2004 edition of the brochures published by the Pro Monument Foundation (ProMo) whenever a Monumento Habrí (Open Monumentday) is organized. Nearly all te historic buildings that are opened to the public on the occasion of Monumento Habrí 2004, have been built on the former hinterland of the Westwerf. These grounds, which were hardly built on round 1860, stretched westward from the St. Anna Bay, and were situated to the north of the present Frederikstraat.
