In the last decade, macrobotanical remains from meters-thick infills of riverbeds excavated at two archaeological sites in Brussels were extensively studied. To the north of the city centre, at the site of Tour & Taxis, the remains of a meandering river arm was brought to light. Archaeological finds indicate human occupation during the Gallo-Roman period, while in the early medieval period anthropogenic activities declined and the river arm gradually disappeared from the landscape. The second site is situated within the ancient city centre of Brussels, in the area of the medieval harbour on the Senne, where several phases of the medieval river were uncovered. The oldest layers document on the towns’ earliest developments while the most recent deposits shed light on the late medieval city and its urbanisation. The results of the macrobotanical analyses of these two similar contexts from a rural and an urban site illustrate the potential and challenges of archaeobotanical studies of fluvial deposits and highlight the importance of an integrated taphonomical approach. The exceptional diversity of the plant material and its excellent waterlogged preservation offer unique insights into various aspects of daily life through time. Plant remains from both sites consist of a mixture of naturally accumulated material and remains from anthropogenic deposits, including animal dung, human excrements, fuel, domestic and artisanal waste. Due to the diverse origins of the botanical material that ended up in the water, the assemblages not only provide information on the local vegetation history but also on agriculture, food economy, trade, ornamental plants and waste management. In addition, numerous remains from the urban Senne deposits give material evidence for textile working and dyeing with plants along the riverbanks for more than three centuries.
