What is bricked up meaning?

To "brick up" something means to block or seal off a doorway, window, or other opening using bricks. This is typically done to prevent entry to a space, either for security reasons or because the space is no longer needed. For example, a brick wall may be built to block off an unused fireplace, or a doorway may be bricked up to prevent unauthorized access to a building.

The term "bricked up" can also be used as an adjective to describe something that is permanently blocked or sealed off, such as a bricked-up chimney or bricked-up window. In some cases, the term may also be used metaphorically to describe a situation where progress or opportunity is being blocked, such as when bureaucracy or red tape "bricks up" the path to success.
