The past is often a refuge from the present. Whether it’s where you were two weeks ago or 10 years ago, there’s a certain security that comes from the certainty of then.

Perhaps that’s why a team of designers recently looked at the now-ruined castles of Middle Ages Europe, lifting the fortifications up from their dilapidated states and digitally reimagining the structures as they were in their heyday.

Though a semblance of their former glory remains, today, whether through combative slights or mere neglect, once-fortified sites from Ireland to Romania have degraded. The ruins sit on hilltops and abut cliffs—whatever best gave them dominion over the surrounding lands. They were the homes of rulers and landed elites, replete with turrets, towers, parapets, and—of course—very burly walls.

Now you can envision how these once-great fortresses may have looked in their heyday, before the ravages of time took hold. Seven European castles were virtually rebuilt, restoring them from their keeps to their baileys. Architects pored over old paintings, blueprints, and other research documents that describe the strongholds, then offered their opinions to the NeoMam Studios design team, which digitally revived the structures from the ground up.

From a northern French fortification built by Richard I of England to a castle once occupied by Vlad the Impaler, these buildings are reconstructed in a way that inspires you to think about how they once stood—seemingly permanent sentinels over their kingdoms, resolute even in the face of time itself.

Croatia’s Samobor Castle was traded among Central European elites for centuries, before it was sold to the city of Samobor for about $200 in 1902. The moat, entryway, and walls are all that remains.

Today a decayed, ivy-covered ruin, Menlo Castle was a stately home in 16th-century Ireland.

Little remains of Scotland’s Dunnottar Castle, built on a promontory overlooking the North Sea. It was once occupied by the Picts, then the Vikings, and finally the Scots, and even sheltered Scotland’s crown jewels during the English Civil War.

Built at the end of the 12th century by Richard I of England, Château Gaillard was destroyed 400 years later by Henry IV of France. In its glory days, even “château” was an understatement.

A fire in 1780 tore through Slovakia’s Spiš Castle, leaving it a semblance of its former self. But during the Renaissance, it was one of the largest castles in Central Europe.

Today, a distinctive 115-foot-tall tower remains standing over the ruins of Poland’s Olsztyn Castle. Once the property of King Władysłow II Jagiełło of Poland, the castle fell apart following 17th-century wars with the Swedes.
