Akkerman Fortress (Belgorod-Dniester Castle)

More than nine hectares of stone walls, three rings of defence, two dozen towers, and twenty-three centuries of history concentrated in a single location. This is Ukraine’s largest fortress — and one of the few that grew directly on the ruins of an ancient Greek city.

Akkerman Fortress (also known as Bilhorod-Dnistrovskyi Castle) stands on the rocky shore of the Dnister Estuary. A place where Greeks, Genoese, Moldavians, and Ottomans all left their mark — and where every stone has a story to tell.

Location Card

What It Is & Why Come Here

Akkerman Fortress is no ordinary castle: it is Ukraine’s undisputed record-holder, the largest fortress in the country by area. It rises on the rocky bank of the Dnister Estuary and impresses from the first glance — massive walls stretching into the distance, mighty towers, several inner courtyards.

People come here to feel real history: climb the towers, walk the fortress yards, look out over the estuary from the ramparts and try to imagine twenty-three centuries of events that unfolded here. The sea breeze adds a final touch — the fortress fits perfectly into any road trip through Odesa Region.

The fortress is divided into several courtyards: a civilian yard (where townspeople took shelter during attacks), a garrison yard (for the military), and the citadel — the most heavily fortified core of the castle.

History: From Greek Tyras to Ottoman Akkerman

It all started in antiquity: on this very spot stood the Greek city of Tyras, founded around the 6th century BCE. That means the site’s history spans approximately 2,300 years — an extraordinary antiquity even by Ukrainian standards.

The stone fortress itself was built over several eras. The citadel is associated with the Genoese period of the 13th–14th centuries, while the main fortifications were raised under Moldavian rule in the 15th century. The city and fortress later fell under the Ottoman Empire — it was the Turks who gave it the name Akkerman, meaning «white stone.»

Today

In 1944 the city was renamed Bilhorod-Dnistrovskyi, and the fortress became a museum-reserve. Since July 2019, Tyras and Akkerman Fortress have appeared on UNESCO’s Tentative List of World Heritage Sites. Today it is one of the most visited attractions in southern Ukraine.

Legends & Local Lore

A fortress with this much history is naturally full of legends.

1. Ovid’s Tower

One of the towers is traditionally linked to the Roman poet Ovid, who was exiled to the shores of the Black Sea (Pontus). Historians doubt he ever came specifically here, but the legend has proved remarkably persistent — and the name is undeniably romantic.

2. The Maiden’s Tower

A classic castle motif: the legend of a ruler’s daughter imprisoned (or who perished) in a tower because of forbidden love or betrayal. The details vary in different tellings, but the story adds a layer of tragic poetry to the stone walls.

3. Underground Passages Beneath the Estuary

Stories have long circulated about secret underground passages supposedly running from the fortress under the estuary or far beyond the walls. Some cellars genuinely exist; the rest is folk imagination that is hard to verify.
