12th Century
Windsor Castle provides early examples of galleted masonry having both flakes of flint inserted into the mortar and oyster shells laid in the bed joints. Henry II started much of the castle's construction and subsequent rulers added to this. One notable addition is King Henry VIII's Gate circa 1510 - 1520.
Most of the original galleting has been replaced over the centuries, much of it in a most unsatisfactory manner by the architect Wyatville in the 1820's. Fortunately some of the original has survived to provide a guide for future maintenance.
Example of the galleting to be found at Windsor Castle
The Church of St Michael and All Angels, Aylsham, Norfolk.
A brief history of galleting
Many galleted stone buildings were erected from the 13th to the 16th century. Amongst the earliest is this church in Aylsham. Churches frequently display a range of variations in the masonry of a single building due to developments over the centuries and this is the case here.
The Chapel of Apliki, Kato Drys, Cyprus.

The ruined Chapel of Apliki is believed to date from the Venetian period 1489 - 1570/71 when Cyprus was enjoying wealth brought by trading.
The picture above illustrates quite densely packed gallets in the joints.
La Fosse, St. Martin, States of Guernsey.
This building dates from circa 1770 when, in the 18th century, galleting was enjoying something of a revival.
The black pebbles create an unusual form of galleting.

Knole House, Sevenoaks, Kent
Knole was built by Thomas Bourchier, Archbishop of Canterbury, during the period 1456 - 1486. The masonry is of Kentish ragstone with gallets formed from the same stone. The picture on the right is of the original material.

Arundel Road, Dorking.
This mid Victorian boundary wall is of flint with ironstone gallets that are thought to have been used for decorative purposes.
13th century
15th century
Henry VIII acquired the property and extended it, forming a new front and entrance courtyard during the period 1543 - 1548 and built using materials and galleting to match the original.
This style of masonry was in use in Kent from the 14th to the 19th century although some of the early work was of galleted random rubble walling.
Galleting throughout Great Britain largely dates from the time of the Norman Conquest through to the Victorian era although pinning that was extensively used in dry stone walling existed for millennia prior to this.
St. Mary and All Saints Church, Dunsfold, Surrey.
This beautiful church was built circa 1270. Although it has been repointed it is thought that the original ironstone gallets were salvaged and reused.

14th century
The Pilgrim Chapel, St. Marys Abbey, Kent.
This wall is of dressed Kentish ragstone with oyster shell gallets in both the horizontal and vertical mortar joints.
It was built circa 1320.
St. Michael's Church, Beccles, Suffolk.
Built in the second half of the 14th century the walls are built of knapped flint with flint gallets.
18th century
19th century
The picture above shows a wall believed to date from circa 1270. Knapped flints are used in the construction with slim flakes of flint inserted into the relatively narrow mortar joints.
Beccles and District Museum, Suffolk
The original building constructed in the 16th century had a thatched roof. Major restoration in 1762 resulted in the new front wall with its squred flints coursed with bricks and having flint gallets.
This is a grade I listed building.

16th century
Bourne Mill, Colchester, Essex.
Bourne Mill was constructed as a fishing lodge in 1591 but was converted into a water mill in the 19th century.
The masonry is of roughly squared stone and assorted bricks, galleted with flint.
The image on the right illustrates brickwork galleted with small pieces of ironstone.
The building is located in the County of Surrey where this is known as garnetting. Although common in stonework the use of galleting in brickwork is quite unusual.
Shere, Surrey.

The Flint House, Buckinghamshire.
20th century
Riverhead Village Hall
The walls of this property demonstrate a new and exciting way to use flint masonry for a new era.
The sizes and shapes of the flints are graded throughout the height of the building with the galleting developing, again through the height, to accentuate the changing appearance of the walls.

New buildings of this era are occasionally constucted with galleted masonry. Tigbourne Court designed by Sir Edwin Lutyens is an early example. In the case of this village hall, which is brick built, Kentish ragstone panels are incorporated into the front wall to reflect the local vernacular.
St Johns Church, Sevenoaks, Kent
The photograph above shows one area of the flint masonry in which the flints are set closely together with neat galleting.

It was not uncommon for Victorian churches to have galleted masonry; in this case in Kentish ragstone random rubble.
A large part of Westminster Cathedral was built at this time.
Cement is introduced and seen as superior to lime mortar. Much of the understanding of working with lime mortar is lost. In Mexico gallets were used unsuccessfully in conservation work to identify reconstructed walls. Gallets are still in general use in some countries such as Cyprus.
