The kingdom combines modern Arab culture and the archaeological legacy of five thousand years of civilisation. The island is home to forts including Qalat Al Bahrain which has been listed by UNESCO as a World Heritage Site. The Bahrain National Museum has artefacts from the country's history dating back to the island's first human inhabitants some 9000 years ago and the Beit Al Quran (Arabic: بيت القرآن, meaning: the House of Qur'an) is a museum that holds Islamic artefacts of the Qur'an. Some of the popular historical tourist attractions in the kingdom are the Al Khamis Mosque, which is one of the oldest mosques in the region, the Arad fort in Muharraq, Barbar temple, which is an ancient temple from the Dilmunite period of Bahrain, as well as the A'ali Burial Mounds and the Saar temple. The Tree of Life, a 400-year-old tree that grows in the Sakhir desert with no nearby water, is also a popular tourist attraction.
