The architecture of Denmark has its origins in the Viking Age, revealed by archaeological finds. It was established in the Middle Ages when first Romanesque, then Gothic churches and cathedrals, were built throughout the country. During this period, brick became the construction material of choice for churches, fortifications and castles, as the country had little access to stone.
Under the influence of Frederick II and Christian IV, both of whom had been inspired by the castles of France, Dutch and Flemish designers were brought to Denmark to improve the country's fortifications. They increasingly transitioned to building magnificent royal castles and palaces in the Renaissance style. In parallel, the half-timbered style became popular for ordinary dwellings in towns and villages across the country.
