Thomas Archer is responsible for some of the most celebrated country houses, churches and garden buildings in this country, yet remains one of the most overlooked architects of this period. This new study of Archer’s life and works reconsiders each of his designs afresh, and features new documentary evidence on many of his works. It also examines his architecture within its original landscape contexts, discussing his awareness of garden design and his potential role in the layout of the gardens surrounding his buildings. This is set against a backdrop of his previously unknown travel across Europe, his vibrant career at court, and his role in designing several London churches. Richly illustrated and incorporating significant new findings, this work shines new light on an undervalued architectural master of the English Baroque.
