Moreover, bollards contribute to aesthetic enhancements within urban design. While their primary purpose may be utility, bollards come in a variety of styles, colors, and materials. This allows city planners and designers to choose options that complement the surrounding architecture and landscape.

For example, in historical districts, traditional-style bollards can evoke a sense of nostalgia and character, while modern designs can enhance contemporary urban settings.

Manholes are usually round, primarily because roundness is the best shape to resist the compression of the earth; covers are round because they are easier to manufacture than square or rectangular shapes, they are easier to move by rolling, and they can't fall into the opening.^[5] But in the United Kingdom they are nearly always square, or rectangular, in shape, at least at street level. Manholes can also be found in a triangular shape (e.g. in Cambridge, and surrounding villages).^[6]
