Where the European Union meets its longest land frontier

From the fells of Lapland to the mouth of the Evros, one line separates the European Union from its eastern neighbours. Celbet.eu follows that line on the ground - the rivers it traces, the crossings that open it and the borderlands it shapes.

01 Geography

Crossing points: the line from the Baltic to the Black Sea

A north-to-south tour of the line: Narva, Terehova, Medininkai, Terespol, Medyka, Vysne Nemecke, Zahony, the Prut bridges and the road to Istanbul.

02 Borderlands

Along the border: twin towns, rail yards and wild places

Twin towns and facing fortresses, the break-of-gauge rail yards of Zahony, primeval forest and delta marsh - the regions the frontier made.

The line, from top to bottom

The European Union has no eastern coastline, only a line on land - and it is a remarkable piece of geography. It begins in Lapland, at the fell where Finland, Norway and Russia meet, and runs south through taiga, lake country and bog along the Finnish-Russian border, the longest single section of the whole frontier at roughly 1,300 kilometres. Interrupted by the Gulf of Finland, it resumes at Narva, where two medieval fortresses face each other across a river, and continues down the Baltic states - Estonia and Latvia against Russia, Lithuania against Belarus.

In Poland the line settles onto the slow water of the Bug river, then climbs into the wooded ridges of the Carpathians where Poland, Slovakia and Hungary meet Ukraine. From the Tisza crossing at Zahony it drops onto the plain, follows the Prut river along the whole length of the Romanian-Moldovan border, and dissolves into the reed channels of the Danube delta at the Black Sea. The final act belongs to the south: the old Istanbul road through Svilengrad and Kapitan Andreevo, and the Evros river carrying the Greek-Turkish border down to the Aegean.

Along this line lie eleven member states, ten neighbouring states, twin towns and transshipment yards, primeval forest and delta marsh - and the limited set of crossing points where the frontier can legally be passed. Everything the EU regulates about goods becomes physical at those crossings, which is why this site keeps one article about the customs machinery behind the line alongside the geography.

Read it in order: the crossing points map the line from the Baltic to the Black Sea. Along the border covers the regions the line shapes - the twin towns, the rail yards, the wild places. Visiting the frontier is the field guide for seeing it yourself, and the customs article explains what actually happens to a truck at the line.

Frequently asked questions

Short answers on the EU's eastern land border - where it runs, what it follows and how to see it.

Q·01

Which EU countries share the eastern land border?

Eleven member states sit on the EU's eastern and south-eastern land border: Finland, Estonia, Latvia, Lithuania, Poland, Hungary, Slovakia, Croatia, Romania, Bulgaria and Greece.

Q·02

Where does the EU eastern land border begin and end?

It begins in Lapland at the point where Finland, Norway and Russia meet, and ends where the Evros river carries the Greek-Turkish border into the Aegean Sea.

Q·03

What is the longest single section of the border?

The Finnish-Russian border, at roughly 1,300 kilometres of taiga, lake and bog - the longest external land border any EU state shares with a single neighbour on the eastern frontier.

Q·04

Which rivers form parts of the border?

The Narva between Estonia and Russia, the Bug along eastern Poland, the Tisza at the Hungarian-Ukrainian crossing, the Prut along the entire Romanian-Moldovan border, the Danube and its delta, and the Evros/Maritsa between Greece, Bulgaria and Turkey.

Q·05

Can you visit the border?

Yes - fortress towns like Narva and Przemysl, the Bialowieza forest and the Danube delta all sit on or beside the line and are ordinary destinations. Only the marked border strip itself and the checkpoints have restrictions.
