Henry travelled less than previous kings, seeking a tranquil, more sedate life and staying at each of his palaces for prolonged periods before moving on. Possibly as a result, he focused more attention on his palaces and houses; Henry was, according to architectural historian John Goodall, "the most obsessive patron of art and architecture ever to have occupied the throne of England". Henry extended the royal complex at Westminster in London, one of his favourite homes, rebuilding the palace and the abbey at a cost of almost £55,000. He spent more time in Westminster than any of his predecessors, shaping the formation of England's capital city.
