In this chapter, we explore how individuals associated with the House of Orange-Nassau expanded their power into new territories through their use of physical spaces, and their organisation and practices of material culture within them. Here we explore a wide range of examples, including military installations, architecture, gardens, agriculture, religious patronage, and monuments that spread the power of the House from its base in the northern Netherlands to German lands, England, Scotland, Ireland, and Russia. We argue that new sites for the display of Orange-Nassau power and identity were not always explicitly directed by those leading the House, but instead involved many interlocutors who were making – sometimes literally – meaning for the House according to their own needs and views, through their actions, designs, and constructions in new geographical spaces.
