Tower of Calais (Tour de Calais), tower to right, two ships in the sea to left and in center, from 'Views of seaports' (Vues de ports de mar) 1647

"Tower of Calais (Tour de Calais)" is an etching by Italian artist Stefano della Bella, created in 1647. The artwork is part of a larger series of etchings titled "Views of Seaports" (Vues de ports de mar). This etching depicts a towering fortified structure, possibly a castle or a tower, against a backdrop of a churning sea. Two small boats with sails are in the foreground, adding to the dramatic scene of the seaport. The use of etching, a printmaking process where acid is used to create the image on a metal plate, gives the artwork a distinct texture. This is a fine example of Della Bella's skillful depiction of architectural structures and seascapes. The etching is a great example of his versatility as an artist, as he was known for his work in landscape and portraiture.
