Medieval Bricks and Roofing Materials: Solid as a Rock?

The architecture of the medieval period stands as a testament to the ingenuity and craftsmanship of our ancestors.

While the grandeur of castles and cathedrals often steals the spotlight, it is the humble yet crucial building materials that form the foundation of these structures.

Bricks in Medieval Architecture

The Emergence of Bricks

Medieval bricks marked a significant departure from the preceding Roman period, which primarily used stone and timber for construction.

The resurgence of brick usage during the Middle Ages can be attributed to various factors, including technological advancements, economic feasibility, and ease of production. The most common types of bricks in medieval Europe were made from clay.

The reintroduction of bricks into European construction was facilitated by technological advancements. The invention of the horse-powered clay mill in the 12th century significantly improved clay processing. This innovation allowed for more efficient extraction of clay and its preparation for brickmaking.

Economic Feasibility

The use of bricks in medieval construction was also driven by economic considerations. Bricks were often more affordable than stone, making them an attractive choice for a variety of building projects, from churches to fortifications.

Types of Medieval Brick

Common bricks were the most widely used type of bricks in medieval Europe. They were typically made from locally available clay and were used for everyday construction. These bricks had irregular shapes and varied in size, making them a cost-effective choice for a range of applications.

Decorative Bricks

Medieval builders often used decorative bricks to add ornamental features to their structures. These bricks were carefully crafted and sometimes featured intricate designs, including patterns and symbols. They were commonly used in religious buildings, such as cathedrals and monasteries.

Notable Examples of Medieval Brick Architecture

Flint in Medieval Architecture

Flint is a sedimentary rock often associated with medieval architecture in parts of Europe, such as England and Scandinavia.

Its use in construction was influenced by its abundance in certain regions, particularly in the British Isles. Flint was valued for its hardness and ability to form sharp edges when broken, making it a suitable material for building.

It was primarily used as a walling material, often in combination with other materials like bricks, timber, or thatch. Flint walls could be built in various styles, including herringbone patterns or irregularly stacked shapes, depending on regional traditions.

Flint Knapping

The process of shaping flint for construction is known as flint knapping. This involved carefully selecting and shaping flint nodules to create building blocks that could fit together to form sturdy walls. Flint’s hardness made it a durable and resilient choice, ideal for fortifications and churches.

Norwich Castle

Norwich Castle in Norfolk, England, is an iconic example of medieval flint architecture. Built during the 12th century, the castle features massive flint walls that showcase the fortification capabilities of this material.

St. Mary’s Church, Harmondsworth

St. Mary’s Church in Harmondsworth, England, is a striking example of how flint was used in combination with brick to create intricate and aesthetically pleasing patterns on the walls. The church’s architecture demonstrates the versatility of flint as both a structural and decorative element.

Wattle and Daub Construction

Wattle and daub is a construction method that has been used for thousands of years, with origins dating back to the Neolithic period. In medieval Europe, wattle and daub was a common building technique for a variety of structures, from simple cottages to larger dwellings and barns.

The wattle component of this construction method involves weaving thin, flexible branches or sticks into a lattice framework. In most cases the wattle is split hazel rods, you will see this technique in wattle hurdles. These wattle panels are fixed to a wooden frame, creating a sturdy and flexible structural system.


Daub is a mixture of materials, including clay, mud, straw, and sometimes animal dung, which is applied to the wattle framework. The daub acts as both insulation and protection against the elements.

Wattle and Daub is a tried and tested method of buildings walls in homes.

Advantages and Limitations of Wattle and Daub

Wattle and daub construction was popular due to its simplicity and the use of readily available materials. It provided good insulation and was well-suited for regions with a temperate climate.


While wattle and daub was cost-effective and easy to construct, it had some limitations in terms of durability and resistance to fire. As a result, it was often used for less permanent structures or as infill for timber-framed buildings.

Notable Examples of Wattle and Daub Architecture

Cruck houses, found in England and other parts of Europe, often used wattle and daub for their walls. These buildings featured a distinctive curved wooden frame (the cruck) that supported the structure, with wattle and daub infill between the frames.

Medieval Cottages

Throughout medieval Europe, wattle and daub cottages were a common sight. These simple yet charming structures were often home to rural communities and showcased the adaptability of wattle and daub construction to a range of building types.

Dry Stone Construction

Dry stone construction is a building method that dates back thousands of years and was widely used in medieval Europe. It involves stacking stones without the use of mortar or other binding materials, relying on the careful arrangement of stones to create stable and durable structures.

Drystone Walls

One of the most common uses of dry stone construction in the medieval period was for building walls, fences, and enclosures. The stones were carefully selected and stacked to create walls that were not only functional but also visually appealing.

Corbelled Construction

In addition to walls, dry stone construction was used to create corbelled structures, including watchtowers, bridges, and fortified towers. Corbelled construction involves gradually offsetting stones to form an arch or a dome, creating sturdy and self-supporting structures.

Drystone walling has been used for thousands of years.

Advantages of Dry Stone Construction

Dry stone construction offered several advantages, including its resilience in various weather conditions and the sustainable use of locally sourced materials. This method also allowed for flexibility in design and repairs, as damaged stones could be replaced without the need for mortar.

Notable Examples of Dry Stone Architecture

Hadrian’s Wall, built during the Roman era but maintained and expanded during the medieval period, is a prominent example of dry stone construction. This long defensive wall in Northern England used locally sourced stones to create a formidable barrier.

Ireland is home to numerous stone forts, such as Grianán of Aileach and Dun Aonghasa, which showcase the durability and impressive craftsmanship of dry stone construction.

Roofing Materials in Medieval Architecture

Thatch Roofing

Thatched roofing, made from natural materials such as straw, reeds, or heather, was a common choice for roofing in medieval Europe. Thatch provided excellent insulation and was readily available in many regions.

Shingle Roofing

Shingle roofing, made from wooden shingles, was another prevalent roofing material in medieval architecture. These shingles were crafted from split logs and were layered to create a durable and waterproof roofing system.
