Gurdwaras:

Perhaps Singh's most lasting legacy was the restoration and expansion of the Harmandir Sahib, the most revered Gurudwara of the Sikhs, which is now known popularly as the "Golden Temple".Much of the present decoration at the Harmandir Sahib, in the form of gilding and marblework, was introduced under the patronage of Singh, who also sponsored protective walls and water supply system to strengthen security and operations related to the temple. He also directed construction of two of the most sacred Sikh temples, being the birthplace and place of assassination of Guru Gobind Singh – Takht Sri Patna Sahib and Takht Sri Hazur Sahib, respectively – whom he much admired.
