The Mausoleum of Ayatollah Khomeini houses the tomb of Ruhollah Moosavi Khomeini and Ahmad Khomeini, his second son who died in 1995. It is located to the south of Tehran in the Behesht-e Zahra (the Paradise of Zahra) cemetery. Construction commenced in 1989 following Khomeini's death on June 3 of that year. It is still under construction, but when completed will be the centerpiece in a complex spread over 5,000 acres (20 km2),housing a cultural and tourist center, a university for Islamic studies, a seminary, a shopping mall, and a 20,000-car parking lot. The Iranian government has reportedly devoted US$2 billion to this development.

The shrine is surrounded by a large rectangular plaza which has been designed to hold vast numbers of visitors.

The dome is supported by eight large marble columns that circle the sarcophagus, that together with other smaller columns support the space frame ceiling.
