Cor Noltee was educated at the Hague art academy, where he was especially influenced by Willem de Zwart (1862-1931). In 1937, he settled in Dordrecht, where he was a well-known figure for his work as well as for his Bohemian appearance. Noltee formed the basis for a local revival of impressionism. He was known as "the Dordtse Breitner”, because of his kinship with that painter in terms of style and subjects. He usually painted the old cities of Rotterdam and Dordrecht, and the river landscape in the area. Around 1961, Noltee went into a different artistic direction. His last works had a decidedly expressionist character. This painting shows the Delftse Poort and the traffic of that time.
