Mary's worries about the position of her son affected her health. To cut her own expenses in the interests of her brothers, she announced her intention to abandon two of the four palaces at her disposal. In July 1654, she went to a water resort, where she spent a few weeks, and then came to visit her brother Charles in Cologne, where his court was located. She returned to the Netherlands in October, but in July 1655 she again went to Charles in Cologne, visited the fair in Frankfurt incognito and returned home on 15 November. In January 1656, Mary went to Paris, where her mother and younger sister Henrietta lived, and was received with all honors at the French court.
