The temple is surrounded by a large Sarovar (manmade lake), known as the AmritSar (Lake of Holy Water or Immortal Nectar). There are entrances to the temple on all four sides, signifying the importance of acceptance and openness; ostensibly, this concept is reminiscent of the tent of Abraham in the Old Testament—his tent was open on all four sides in order to be able to welcome travelers from all directions. Inside the temple complex there are many shrines to past Sikh Gurus, Saints and martyrs (see map). There are three holy trees (Bers) each associated with a historical event or Sikh saint. Inside the temple there are many memorial plaques that commemorate past Sikh historical events, saints, martyrs and includes commemorative inscriptions of all the Sikh soldiers who died fighting in the two World Wars. For a new visitor the first recommended place to visit is the information Office highlighted (4) on the map and followed by visiting the Sikh Central museum near the main entrance called the Ghanta Ghar Deori (clock tower gate). Anyone who wants to enter the Harmandir Sahib may do so, irrespective of religion, colour, creed or sex. The only restrictions are that the person must not drink alcohol, eat meat or smoke cigarettes or use other non prescription drugs while in the shrine. Visitors are, as well, expected to dress appropriately and everyone must cover their heads as a sign of respect, remove their shoes and socks and enter the temple barefooted. Visitors must wash their feet in the small pool of water as they enter the Harmandir Sahib premises. Head scarves are provided.

In 1988, after Operation Black Thunder, a narrow peripheral strip of land (including buildings) was acquired by the government essentially to create a security belt. A large number of people were displaced in the process. However, the project met with a strong resistance from the moderate as well as militant Sikh organisations and the project had to be abandoned, after a senior Government engineer, connected with the project, was killed. The project was revived only in 1993 by the Deputy Commissioner Karan Bir Singh Sidhu, who was also appointed as the Project Director of what was popularly described as the Galliara Project. He changed the concept of the periphery from that of a security belt to that of a second parikarma and created a serene landscape that was fully consistent with the ethereal beauty of the Harmandir Sahib. This was done in quiet consultation with the SGPC. The pilgrims today can travel by foot in the Galliara, where no vehicles are permitted.
