During this period George took an active interest in matters of style and taste, and his associates such as the dandy Beau Brummell and the architect John Nash created the Regency style. In London Nash designed the Regency terraces of Regent's Park and Regent Street. George took up the new idea of the seaside spa and had the Brighton Pavilion developed as a fantastical seaside palace, adapted by Nash in the "Indian Gothic" style inspired loosely by the Taj Mahal, with extravagant "Indian" and "Chinese" interiors.
