Teleporio™ travel intelligence

Chios produces the world's only mastic resin — a natural gum with a distinctive pine flavour harvested from lentisc trees that grow nowhere else on earth. The island has been commercially significant for this product for over 2,500 years.

Island symbol and meaning

The mastic tree branch with its resin tears represents Chios's most singular contribution to world culture: a product that exists nowhere else on earth. Mastic (mastiche) is the dried resin of the Pistacia lentiscus var. chia — a variety of the lentisc shrub that produces its characteristic resin only when grown in the southern villages of Chios, in a microclimate and soil type that has never been successfully replicated anywhere else. Attempts to cultivate mastic trees in other Mediterranean countries consistently fail to produce the resin.

The harvesting process is as it has been for millennia: farmers cut the bark of the trees in a pattern called kentima, and the resin bleeds out and hardens in the air into translucent tears. These tears — ranging in size from small droplets to marble-sized chunks — are gathered by hand from the white clay ground spread beneath the trees to catch the drip. The harvest happens in summer, and the product is then sorted, cleaned, and processed into the dozens of forms in which it is consumed: chewing gum (the word 'masticate' derives from mastic), liqueur, cosmetics, pharmaceuticals, and food.

The Genoese who controlled Chios in the medieval period understood the commercial value of mastic and protected its production jealously, establishing a system of fortified villages — the Mastichochoria — specifically to control and protect the mastic workforce. These villages, built according to a distinctive defensive plan with shared outer walls and no external doors, survive today and are among the most remarkable examples of medieval settlement planning in Greece.

History

Chios has been inhabited since the Neolithic period. In antiquity it was one of the most prosperous and cultured of the Aegean islands, credited as the birthplace of Homer — though several cities competed for this honour. The ancient Chians had a sophisticated literary and artistic culture and, unusually, maintained a sizeable slave trade within a semi-democratic political system.

The Genoese period (1346–1566) was the most commercially significant in Chian history. The Genoese established the Maona — a joint-stock company — to administer and profit from Chian mastic production. They built the fortified mastic villages of the south (Pyrgi, Mesta, Olympi, Vessa) as production and defence complexes, and constructed the Kastro (castle) of Chios town. The island became one of the most profitable commercial outposts in the eastern Mediterranean.

Ottoman conquest in 1566 maintained the mastic monopoly under Ottoman administration — the product was particularly valued in the Ottoman court and harem. Chian merchants flourished as an Ottoman commercial elite, trading across the empire and into Europe. The island's educated merchant class produced several figures of the European Enlightenment.

The Chios massacre of 1822 was one of the most devastating events of the Greek War of Independence. Following a failed local uprising, Ottoman forces killed approximately 40,000 inhabitants and enslaved a further 70,000. The population of the island was reduced from 120,000 to around 30,000. The event shocked European public opinion and was immortalised in Eugène Delacroix's painting 'Scene from the Massacre of Chios' (1824). Victor Hugo wrote about it; Lord Byron referenced it in his poetry. The massacre accelerated international support for Greek independence.

Chios reunited with Greece in 1912. The island rebuilt its economy around shipping — the Chian shipowning families (Onassis's family had Chian roots; the Livanos, Chandris, and Lemos families are all Chian) became some of the most powerful in the global maritime industry — and mastic production, which was granted EU Protected Designation of Origin status in 1997.

Culture

The Mastichochoria — the mastic villages — represent a unique form of medieval urban planning. Pyrgi is the most celebrated: its facades are decorated with a geometric pattern called xysta, created by scratching grey mortar to reveal the white plaster beneath, in a technique unique to Chios. The patterns — diamonds, stars, waves — cover entire house facades in a system that is simultaneously decorative and, historically, a method of camouflage and village identification.

Chios has an unusually strong intellectual tradition for an island of its size. The island's commercial prosperity funded libraries, schools, and a connection to European intellectual networks that made it one of the best-educated communities in the Ottoman-ruled Greek world. The Chian merchant diaspora — in Genoa, Amsterdam, Marseille, and London — maintained schools and cultural institutions that preserved Greek language and learning through the Ottoman period.

The Nea Moni monastery on Chios, founded in the eleventh century by Emperor Constantine IX Monomachos, houses some of the finest Byzantine mosaics in existence — considered among the masterpieces of the Macedonian Renaissance style. It is a UNESCO World Heritage Site.

Frequently asked questions

What is mastic and why does it only grow on Chios?

Mastic is the dried resin of Pistacia lentiscus var. chia, a variety of the lentisc shrub that produces its characteristic resin only in the southern villages of Chios. The microclimate and soil composition of the Mastichochoria region — combined with centuries of agricultural expertise — create conditions that have never been successfully replicated elsewhere. Mastic from other regions does not produce resin.

What are the Mastichochoria?

The Mastichochoria are a group of medieval villages in southern Chios built specifically to house and protect the mastic workforce. Constructed by the Genoese in the fourteenth and fifteenth centuries, they have a distinctive defensive design with shared perimeter walls, no ground-floor windows, and a central tower for refuge. Pyrgi is the most famous, known for its xysta facade decorations.

What happened in the Chios Massacre of 1822?

Following a failed Greek uprising in 1822, Ottoman forces killed approximately 40,000 Chians and enslaved around 70,000 more, reducing the island's population from 120,000 to roughly 30,000. The event was documented in European press and immortalised in Delacroix's famous painting. It became a cause célèbre that increased international support for Greek independence.

Is Chios a tourist destination?

Chios is less developed for mass tourism than many Greek islands, which has preserved its character and authenticity. It attracts visitors interested in history, architecture, and the mastic industry rather than beach tourism. The mastic villages, Nea Moni, and the island's food culture (including mastiha-flavoured products) are the primary draws.
