Nanakshahi bricks
Nanakshahi bricks (Punjabi: ਨਾਨਕਸ਼ਾਹੀ ਇੱਟ; meaning "belonging to the reign of Guru Nanak"), also known as Lakhuri bricks, were decorative bricks used for structural walls during the Mughal era. They were employed for constructing historical Sikh architecture, such as at the Golden Temple complex. The British colonists also made use of the bricks in Punjab.
