Kinsterna Hotel – a 17th-century cistern mansion above Monemvasia

In the hills above Agios Stefanos, a short drive from the fortified rock of Monemvasia, a seventeenth-century manor built with walls thick enough to repel pirates has become one of the most quietly accomplished hotels in the Peloponnese. Kinsterna takes its name from the Byzantine word for cistern – the great water tank at the heart of its inner courtyard – and its past runs through Byzantine, Ottoman and Venetian hands before the estate fell into ruin and was patiently rebuilt. In March 2025 the MICHELIN Guide named Kinsterna among only seven Greek hotels to receive Two Keys in the first-ever Key selection for the country, a distinction it has since held onto. Across fifty-one rooms, suites, residences and a single pool villa, spread through vineyards, olive groves and citrus orchards, the house treats restraint as its real luxury: stone walls, wood-fired cooking, and an estate that still presses its own oil and bottles its own wine.

01The house

Kinsterna Hotel is a five-star hotel in the Peloponnese, near the Byzantine fortress of Monemvasia, surrounded by olive and citrus groves on an estate with a fascinating past spanning Byzantine, Ottoman and Venetian times. Archaeologists date the manor's origins to the middle of the 17th century, with several sections added a century later, visible today in its vaulted ceilings, arched portals and iron vine-hooks, while battlements, gun holes and small defensive openings speak of a house once built to withstand pirates and foreign troops.

After the Ottoman era the estate passed from its owner, Ibrahim Bey, to the Ritsos and Kapetsini families; Lina Kapetsini, the last lady of Monemvasia, lived in the mansion until the late 1970s, after which the property fell into disrepair. Restoration began under its current owners in 2006: working with the Greek Archaeological Service, local craftsmen and traditional building techniques, the team spent four years reinstating the manor before it opened as a boutique hotel. Divercity Architects, who completed the project in 2015, added a cluster of individual dwellings and two villas in keeping with the manor's rural character, and an annex to house the restaurants, bar and conference spaces, their roofscape unfolding the tiled, pitched silhouette of Byzantine Monemvasia across the new buildings.

02Rooms and suites

The MICHELIN Guide counts fifty-one rooms and suites that combine the better points of monastic life — naturally soundproof stone walls and picturesque timber construction — with flat-screen TVs, modern furnishings and decadent bathrooms, all built around the courtyard cistern that gives the house its name. Categories range from compact Manor Rooms and vaulted Byzantine Suites with their own outdoor patios, through Kinsterna Suites and family suites with fireplaces and combined sea and mountain views, to Master, Premium and Deluxe Residences and a single 120-square-metre Kinsterna Pool Villa with a semi-private heated pool.

Insider tip

Seasonal operation (April–November); about a ten-minute drive from the medieval castle town of Monemvasia.

Across every category the hotel repeats a handful of signatures: handmade lace wall tapestry, embossed headboards, herringbone-reed wooden ceilings, marble bathrooms, wooden shutters and centuries-old fireplaces left in place from the original building, alongside war-memorial stonework preserved inside the Byzantine suites.

03Where to eat

Sterna Restaurant sits at the heart of the estate beside the Byzantine cistern, its water lilies and twenty flanking columns giving summer dinners an unusually atmospheric backdrop. The all-day restaurant Mouries, named after the mulberry trees that shade its outdoor tables, serves homemade dishes built on seasonal produce from the estate's own springs and gardens, while Linos Tavern cooks traditional Greek food in a wood-fired oven under the trees, for a looser, more rustic register.

Breakfast is treated as its own event: a Greek spread of sourdough bread, the local ladotiri cheese, savoury tsaitia and pumpkin pies, lalangia, trachanas and rice pudding, finished with prickly-pear juice and a fig tart from the estate's own trees.

04The bar

Mouries Bar runs year-round, pouring wines and cocktails built around the aromatic herbs that grow across the mansion grounds. Up on the Belvedere terrace the view takes in olive trees, vineyard and sea at once — a vista the hotel likes to pair with the Greek poet Odysseas Elytis's idea that an olive tree, a vineyard and a boat are all Greece really needs. Down by the water, the Pool Bar keeps things lighter, with fruit-driven cocktails and small plates drawn from the garden.

05Spa, pool and wellbeing

Kinsterna Spa is tucked into a secluded, quiet part of the hotel, featuring a purifying steam bath, a temperature-controlled whirlpool, wet and dry treatment rooms and razul and water-paradise cabins, built around a traditional Ottoman-style hammam with water cabins and jacuzzis both indoors and out. Treatments lean on the estate's own produce — olive oil, honey and grape extract among the signature ingredients.

Outside, the hotel's pool is built like a castle moat around part of the building, fed in part by a freshwater spring that emerges from the basement and widens into a river-like pool with private relaxation corners, alongside a second, family-friendly pool set among the citrus trees.

06The neighbourhood

Across the lane from the manor, five acres of private vineyard grow native Greek varietals — Kidonitsa, Assyrtiko, Agiorgitiko and Monemvasia — from which the estate bottles its own wine, part of a wider push toward self-sufficiency that also covers olive oil, tsipouro distilling, bread baking and soap-making. The medieval fortress of Monemvasia itself, one of Greece's great castle towns, is only a ten-minute drive away, while the sandy coves of Ambelakia, Pounta, Elafonisos, Gefyra and Pori are all within easy reach for a beach day.

Getting there has become easier in recent years: since summer 2023 Aegean and Olympic Airlines have run direct seasonal flights from Athens to Kalamata Airport, cutting the overland leg of the journey to the Peloponnese considerably.

07Making the most of a stay

Kinsterna operates seasonally, from 2 April to 9 November, with check-in from 3pm and check-out at 11am. Outside the obvious pleasures of the pools and spa, the estate runs its own calendar of farm life — grape harvests, olive pressing and tsipouro-making among them — so it is worth asking what is in season before booking, since the character of a stay here changes with the agricultural year as much as with the weather.

For a weekend. For a lifetime.
