A tall lighthouse or beacon structure that operates during daylight hours to help guide ships, using colors or shapes instead of light.
Compound of 'day' and 'beacon,' referring to a signal visible during daytime. These structures evolved as navigation technology developed in medieval and early modern shipping.
Daybeacons were ingenious solutions for safe coastal navigation before electric lights—sailors could recognize specific patterns and colors from miles away, creating a 'language' written in the landscape.
