Why Yemen still matters.
Yemen's cultural footprint is wildly out of proportion to its current visibility. The Queen of Sheba, Bilqis in Arabic, Makeda in Ethiopian tradition, is associated with the ancient kingdom of Saba, whose capital Marib was a hub of the frankincense and myrrh trade two thousand years before Islam. The Marib Dam, built around the 8th century BCE and rebuilt several times until its final collapse in the 6th century CE, was one of the engineering wonders of the ancient world. The Sabaean, Minaean, Qatabanian and Himyarite kingdoms were trading powers tied to the incense routes that connected Yemen to Petra, Gaza and the Mediterranean. Coffee as we know it traces its origin to the highlands above the Red Sea port of Mocha (Al-Mukha), which gave the bean its global name; the qishr infusion of coffee husks remains a distinctively Yemeni drink.
The physical inheritance is extraordinary. Old Sana'a, UNESCO since 1986, is one of the longest continuously inhabited cities in the Arab world, with brown-and-white tower houses up to nine storeys built of fired mud-brick and gypsum, decorative stained-glass qamariyya windows, and the Bab al-Yemen southern gate fronting the Suq al-Milh (salt market). Shibam in the Hadhramaut valley is a fortified town of 500 mud-brick towers up to 30 metres tall, the highest concentration of pre-modern high-rise architecture anywhere, and remains inhabited today. Zabid, on the Tihama coastal plain, was the seat of one of the great medieval Islamic universities and retains its labyrinthine old quarter despite years of neglect. Marib ruins, Sirwah, the rock-cut palace of Al-Mahwit, the spiral-towered villages of Kawkaban and Thula, Yemen has a density of vernacular and pre-Islamic architecture matched by few countries on the planet.
Then there is Socotra. Geologically separated from the mainland for at least 18 million years, the archipelago sits 250 km east of the Horn of Africa and 350 km south of mainland Yemen. It has 825 plant species of which roughly 37% are endemic, including the iconic dragon's blood tree (Dracaena cinnabari) with its umbrella canopy and red sap, the bottle tree (Adenium socotranum), the Socotran cucumber tree and the frankincense trees. Endemic birds include the Socotra warbler, the Socotra starling and several others; endemic reptiles dominate the herpetofauna. UNESCO inscribed Socotra in 2008. The archipelago has its own pre-Arabic Soqotri language, a fishing-and-pastoral economy, and a culture distinct from mainland Yemen. None of this excuses the war or the suffering it has caused, and that context is named once more in the practical section below, but a five-thousand-year-old civilisation, a unique island ecosystem, and the homeland of coffee deserve description on their own terms.
