The support is a plain-weave fabric of medium-fine weight. The tacking margins were removed during relining. The ground is light gray and is visible in small areas in the middle foreground. The ground beneath the sky, however, is a light pink-brown color and is visible through the paint surface where the overlying paint layer is thinly applied. This colored ground influences the overall hue of the lighter sky, although it is not clear whether the gray layer is applied over the entire support beneath the pink-brown layer, which is not discernible in the lower half of the painting. The paint is applied fluidly and the handling is characteristic of the artist at this date. Low impasto is found in some of the highlights and details; the sky is painted more rapidly and thinly with delicate brushstrokes that reveal the underlying ground through striations in the surface layer. The paint is applied primarily wet-into-wet, although details such as the ripples of the water and the figures have been applied with liquid strokes over the dry underlying surface paint. The tile roofs of the buildings are textured with small drops of paint. The reflections of the buildings in the water are painted wet-in-wet. X-radiographs indicate that the left edge of the Porta Portello in the center of the composition has been shifted slightly.
There is an area of considerable loss in the center of the composition measuring approximately 15.2 x 15.2 cm. Discolored varnish was removed and the painting restored by David Bull in 1993.
