Edward Seymour, the son of the Elizabethan builder of the eastern mansion, undertook the most ambitious phase of construction at Berry Pomeroy Castle. His work concentrated on the northern precipice, where he built the Great Hall and the long gallery above it. This range was intended to redefine the house and present it as a Jacobean residence of considerable scale.
The northern range required substantial engineering due to the steep drop into the Gatcombe Valley. The foundations were cut into the edge of the precipice, and the projecting masonry supports show how the builders compensated for the unstable ground. The surviving walls demonstrate careful ashlar work and a confidence in constructing at height. The tall window bays indicate a design intended to maximise light and provide controlled views across the valley.
The Great Hall formed the principal internal space of the new range. Its proportions suggest a room intended for formal gatherings, with tall windows and a clear vertical emphasis. The hall’s position on the northern edge reflects Seymour’s intention to create a prominent architectural statement rather than a purely functional domestic interior. The hall was designed to anchor the new Jacobean identity of the house.
The long gallery above the hall extended for approximately sixty‑three metres. This length places it among the most ambitious domestic galleries in Devon. Galleries of this type were used for walking, display and social interaction. The gallery’s windows would have provided extensive views over the valley, and its internal length created a significant ceremonial space. The gallery was intended to be one of the defining features of the Jacobean house.
The intended terrace outside the northern façade shows Seymour’s interest in integrating the building with the surrounding landscape. Although unfinished, the surviving platform indicates where visitors would have walked along the edge of the precipice. The terrace would have complemented the gallery above, creating a sequence of spaces designed for movement and outward views.
The northern range was never completed. The walls of the hall and gallery were finished, but the roofing, internal fittings and terrace were abandoned. The exposed masonry and skeletal window frames show where construction stopped. The reasons were financial rather than structural. The Seymour family’s political and economic difficulties in the seventeenth century prevented the completion of the project.
Despite its unfinished state, the northern range remains the most visually striking part of the ruin. The height of the walls, the projecting window supports and the steep drop below create a distinctive silhouette above the valley. The remains illustrate the ambition of Edward Seymour’s Jacobean vision and the architectural confidence of the period. The contrast between the completed Tudor mansion to the east and the unfinished Jacobean range to the north provides a clear record of the family’s changing fortunes.
Edward Seymour’s work represents the final major building phase at Berry Pomeroy Castle. His hall and gallery were intended to elevate the house to a level comparable with other early seventeenth‑century residences. Although never completed, the surviving structures define the modern appearance of the castle and preserve the ambition of the project. The northern range remains the most significant architectural legacy of the third Edward Seymour.
