The place where Sikhs gather to worship is called a gurdwara and literally means the guru's door. A gurdwara meeting place has no specific design. It can be a bare, clean, simple room or an elaborate building, such as the Golden Temple with its marble floors, gilded frescos, and ornate domes. Gurdwaras may be surrounded by fountains, or have a moat used by pilgrims for bathing. There might be a flag marked with the emblem of the Sikh coat of arms. The one necessary feature is the installation of Siri Guru Granth Sahib, the Sikh Scripture.
