A rowlock is a specific way of laying bricks where they are placed on their longer, narrower side instead of flat. This technique is commonly used to create decorative borders, window sills, and wall caps in masonry construction. It's similar to how you might place a book standing up on its end rather than laying flat. Masons use this method to add visual interest to buildings and provide practical solutions for areas that need special brick arrangements. Other terms that describe this include "sailor course" when bricks are placed vertically, or "soldier course" when they're stood upright.
