An old belief says that Bahrain was the location of the Garden of Eden: this majestic tree is considered to be all what is left of it. At over 400 years old, this solitary mesquite tree has survived in the desert for centuries, and is believed to be the site where ancient cults practiced worshipping rituals. A small visitor centre welcomes visitors to the site.

The history of Irvine is not a long one -- in fact, today's growing city celebrated its 40th anniversary in December 2011. But the Irvine region has a long and rich history, dating back to 1878 when James Irvine acquired his business partners’ interests in 168 square miles of future Orange County land for $150,000; today, that amount would equate to $3.56 million. The acquisition created the great Irvine Ranch consisting of 110,000 acres stretching 23 miles from the Santa Ana River to the Pacific Ocean. Visitors can explore the oldest standing structure within the original boundaries of Irvine Ranch, and the first wooden house erected between Anaheim and San Diego at the Irvine Historical Museum. In addition, the Irvine Ranch Historic Park, site of the original Irvine Ranch headquarters, features several of the original structures, including the home of James Irvine II, numerous barns and residential buildings. Step back in time at the La Quinta Inn in Old Town Irvine where 101 rooms of the hotel once served as the silos of a former lima bean and grain warehouse. In 1986, the silos were converted to the hotel. The center hexagonal concrete silos are now the interior corridors serving the rooms located in the exterior facing silos and the tin shed, kept mostly intact including the original main lift, is utilized as the area where the hotel serves breakfast. The hotel has a picture display including a brief history and description of "Historic Old Town Irvine."

The museum is packed with interactive and informative exhibits, and offers unique insight into Oman’s gas and oil production that both kids and adults will find fascinating. Entry is free, and explanations in Arabic and English accompany the displays.
