Burg Maus above Wellmich, Germany

Location: Rhineland

 

Burg Maus Castle is a medieval citadel located on the right side of the river. The construction began in 1356 by Archbishop- Elector of Trier Bohemond II and lasted for 30 years. Its strange name that comes from a German for “mouse” came from a nickname that was given by the counts of Katzenelnbogen who found the castle Katz (German for “cat”) and castle Rheinfels across the river. The castle was intended to secure the lands of Trier against this family. In fact it one of the best fortified fortresses in the valley. Through its long and turbulent history it was never captured despite numerous attacks and sieges. Eventually it fell in disrepair in the 16th century due to lack of necessity and ever changing military tactics. The castle was repaired between 1900 and 1906 by architect Wilhelm Gartner with great attention to restore its original appearance.
 
Today the castle is privately owned and it is not accessible to the public. The castle walls and tower hosts aviary that is home to falcons, eagles and owls. Birds are demonstrated between late March and early October. It is one of the last places in Europe that practices this old tradition.

 

History

Origins and Construction (Mid-14th Century)
Construction began around 1353–1356 under Archbishop-Elector Bohemond II of Trier (also spelled Boemund II) and continued for about 30 years until roughly 1386–1388 under his successors, notably Kuno von Falkenstein.
The castle was originally known as St. Peterseck (or Burg Peterseck), later Burg Deuernburg or Thurnberg/Thurmberg, before acquiring the popular name Burg Maus.
Strategic purpose: It served dual roles in the power struggles along the Rhine:
Enforcing Rhine River toll rights recently acquired by the Electorate of Trier.
Securing Trier’s borders and territorial claims against the powerful Counts of Katzenelnbogen, who controlled nearby strongholds like Burg Rheinfels (directly across the river at St. Goar) and were building Burg Katz (Cat Castle, or Neu-Katzenelnbogen).

This placement created a classic medieval “counter-castle” dynamic. The Counts of Katzenelnbogen, whose name literally means “Cat’s Elbow,” mocked the slower-building Trier fortress as a “mouse” that their “cat” (Burg Katz) would eventually devour. This folklore cemented the enduring cat-and-mouse nicknames for the two neighboring castles.
The site was chosen on a mountain spur for excellent oversight of the Rhine, toll collection, and defense. It was one of the most modern fortifications of its era in the region.

Architecture and Layout
The original design included:
A round bergfried (defensive tower) protecting the vulnerable uphill side.
A shield wall.
Residential buildings and a residential tower (later extended with a fourth story under Kuno von Falkenstein).

The ward contains two main residential structures. Its elevated position and robust construction made it highly defensible.

Late Medieval and Early Modern Period (14th–17th Centuries)
In the latter half of the 14th century, Burg Maus served as one of the official residences for the Electors of Trier.
Unlike many Rhine castles (including its rivals Burg Katz and Rheinfels, which were heavily damaged or destroyed in conflicts like the Thirty Years’ War, Nine Years’ War, and later wars), Burg Maus was never destroyed in battle. However, it gradually fell into disrepair during the 16th and 17th centuries as its strategic importance waned.
By 1719, records describe it as dilapidated and empty—the first documented use of the name “Maus” in contrast to “Katz.”

19th–20th Century: Decline, Auction, and Restoration
In 1806, during the Napoleonic era and secularization, the castle was auctioned off for demolition and used as a stone quarry. Only partial demolition occurred, sparing much of the structure.
Around 1900, architect Wilhelm Gärtner purchased it and undertook a careful restoration (1900–1906), reconstructing it with attention to historical accuracy and using original materials where possible. This makes Burg Maus one of the better-preserved examples of medieval castle architecture in the region.
It suffered additional damage from shelling during World War II but was repaired afterward.

Modern Era and Current Use
Today, Burg Maus is privately owned but open to visitors in limited ways. Since the late 20th century, it has housed an aviary with falcons, owls, and eagles. Falconry demonstrations are a popular attraction for tourists from late March to early October.
It stands as a striking landmark in the UNESCO-listed Upper Middle Rhine Valley, near the famous Lorelei Rock, surrounded by vineyards and offering panoramic views of the river and Burg Katz downstream.

 

Architecture

Historical Context and Construction
Construction began in 1356 under Archbishop-Elector Bohemond II of Trier and continued for about 30 years (completed around 1386–1388) by his successors, notably Kuno von Falkenstein.
The castle was built to enforce Trier’s Rhine River toll rights and secure the Electorate’s borders against the powerful Counts of Katzenelnbogen, who controlled nearby Burg Katz and Burg Rheinfels. Its original intended name was Burg Peterseck (or St. Peterseck), later known as Deuernburg or Thurnberg/Thurmberg, before the popular "Maus" name emerged from the "cat-and-mouse" rivalry.
Unlike many Rhine castles destroyed in wars, Burg Maus was never fully razed. It fell into disrepair in the 16th–17th centuries, was partially quarried after an 1806 auction, and underwent a historically sensitive major restoration (1900–1906) by architect Wilhelm Gärtner, based on a detailed 1578 inventory by Archbishop Jacob von Eltz. It sustained some WWII shelling but was repaired.
Today, it is privately owned, occasionally open for events/tours, and famous for its falconry aviary with birds of prey demonstrations.

Overall Layout and Defensive Architecture
Burg Maus is a compact but sophisticated rock castle (Felsenburg) adapted to its steep, rocky site on a mountain spur. It features a mix of late Romanesque and early Gothic military architecture, with later additions.
Core Defensive Elements:
A prominent round bergfried (keep or watchtower) guards the vulnerable uphill (eastern) side. This is one of the castle’s most striking and prominent features, built in the middle of the shield wall (a thick defensive wall facing the landward approach).
The shield wall with the integrated round tower provided strong protection against attacks from higher ground.
A moat carved into the rock (mentioned in visitor accounts) enhanced defensibility.
Outer walls, battlements, and strategic positioning made it one of the more modern and technically advanced fortifications of its era for controlling river traffic and territory.

Residential and Interior Layout:
The ward (inner courtyard area) contains two main residential buildings.
A square residential tower (also called the palas or main living tower) dominates the west façade (facing the Rhine). It features corner turrets and was extended to four stories during construction. This served as the primary residence for the Archbishops/Electors.
A second residential building complemented the living quarters.
A private chapel along the southern wall.

The castle’s relatively small footprint (it appears modest in scale compared to larger Rhine fortresses) is offset by its tall, imposing cylindrical tower and efficient use of the terrain.

Key Architectural Features and Style
Materials and Construction: Built primarily of local stone, with thick walls typical of medieval military architecture. The round tower and shield wall represent advanced defensive design for the period.
Towers and Turrets: The standout round bergfried contrasts with the square residential tower’s corner turrets, creating a distinctive silhouette visible from the river.
Windows and Façades: Restored windows with red shutters (common in reconstructions) and Gothic/Renaissance influences in later phases.
Style Evolution: Original core shows Romanesque solidity (thick walls, functional design), with Gothic elements in arches/windows and some Renaissance touches from later periods/restorations.
Interior Highlights (from historical inventory and restorations): Detailed records from 1578 describe numerous rooms, their locations, and contents, making it unusually well-documented for a medieval castle. The Knights’ Hall is notable and rentable for events.

Current State and Setting
The restoration aimed for historical accuracy, preserving the medieval character while making it habitable. It retains most of its original structure and design. Surrounded by vineyards and steep wooded slopes, it offers dramatic views over the Rhine, especially from river cruises or the opposite bank.
Its "mouse" nickname, born from rivalry, ironically highlights its endurance compared to the larger "cat" castle nearby.
