Across Cultures and Time: The Shared Defense Philosophy of Prejmer Church and China's Fujian Tulou

Tina recently returned from Romania, and during the trip, saw a fascinating structure, the Prejmer Fortified Church, which immediately brought to mind the Hakka Tulou buildings in Fujian, China. Why the comparison? Although these two architectural styles stem from vastly different cultural backgrounds, they share the core spirit of defense and community. They embody the universal human need for security and collective living space, and both are recognized as important World Heritage Sites!

Prejmer Fortified Church

Located in Brașov, Romania, the church was originally built by German settlers who migrated from Western Europe. Facing frequent raids from the Ottoman Turks and other nomadic groups, they integrated the church into a formidable fortress. The result is a circular structure with sturdy, double-layered defensive walls, which served as both the military and spiritual center for the local residents.

Historically, this church was besieged over 50 times yet was almost never breached! Subsequent studies point to several effective defenses: the two heavy gates protecting the entrance, a long, narrow, 30-meter-long arched passageway, high-mounted loopholes for shooting, and openings for pouring down hot oil or water. These features effectively stopped enemies from charging or scaling the walls, leaving invaders in a hopeless situation.

Even more astonishing, the fortress's interior housed nearly 300 rooms, each corresponding to a house number in the village. These were specifically for villagers seeking refuge. This design allowed residents to enter the shelters quickly and orderly when an alarm sounded, minimizing chaos and confusion during high-stress situations. Besides living quarters, the interior also contained granaries, shops, workshops, and classrooms for schoolchildren. At the very center was the chapel. This setup allowed the community to be self-sufficient and maintain daily life even during long sieges.

Hakka Tulou

These earthen buildings are mainly distributed across the mountainous regions of southwestern Fujian, China. They were built by the Hakka people who migrated south from central China to escape warfare. The architecture was designed to resist attacks from mountain beasts, bandits, and hostile outsiders.

Tulou are often circular, though some are square. Regardless of shape, they are built with a centripetal design, featuring only one main entrance and no external windows on the ground floor—only narrow loopholes for defense. A central ancestral hall (Zutang) forms the core of the interior. The ground floor is mostly used for storage or public space, with residential quarters starting from the third floor and up.

The main construction material: Rammed Earth (Hangtu). This is actually the result of an advanced building technique. The outer walls use red soil mixed with sand, lime, and pebbles, with binding agents such as sticky rice paste, brown sugar, or egg whites added. This "rammed earth" craft gives the Tulou walls extremely high density and toughness, as well as excellent insulation. Residents enjoy a cool interior in the summer and a warm one in the winter. There are even records showing that if the walls developed minor cracks from an earthquake, the material's moisture and pressure could cause them to self-repair! They were also sturdy enough to withstand dozens of cannonball attacks, which would only leave shallow dents without piercing the wall.

Prejmer Fortified Church and Fujian Tulou Comparison

Similarities between the two buildings include:

1. 1. Centripetal Layout: Both structures adopt a centripetal layout, with the core serving as a center of faith—the Hakka Ancestral Hall (Zutang) in the Tulou and the chapel/worship center in the European church-fortress.
2. 2. World Heritage Status: Both are recognized as UNESCO World Heritage Sites.
3. 3. Defensive Structure: Both feature thick walls with defense openings (loopholes) located high up for attack.

Differences include:

1. 1. Building Materials: The materials differ (Hangtu (Rammed Earth) versus stone and brick).
2. 2. Function: The church-fortress served as an emergency temporary refuge for the entire village, whereas the Tulou was a place for a cohesive family/clan to live together permanently.
3. 3. Scope/Typology: The church-fortress is a specific, unique case, while the Tulou represents a regional characteristic architecture developed by an entire ethnic group in a specific area.

These two incredible buildings are not merely for "living" or "defense." They are powerful embodiments of community and family cohesion. By learning about them, hopefully, we can look at these precious cultural treasures from a new perspective. They also inspire us today to reflect on using natural, sustainable building materials that offer both security and comfort, alongside practical disaster preparedness strategies.

Easter Egg

On December 1, 2025, Hamstein the hamster arrived in Romania,
eager to see the legendary fortified church.
She actually arrived the day before, but because it was Sunday,
the church was reserved for worshippers and closed to visitors.
So, she had to come back the next day!
Once she saw the entire interior design,
she thought, "Wow, this is truly amazing!"
