Definition: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Input: Passage: In 1898 the firm designed St Oswald's Chambers in St Werburgh Street, Chester, and this was followed by further buildings in the city. In 1902–03 Douglas built St John the Evangelist's Church, in the village of his birth, Sandiway. It was built on land owned by Douglas and he paid for the cost of the chancel and the lych gate. In 1899 the Diamond Jubilee Memorial Clock, constructed in open wrought iron, was erected on the Eastgate in Chester to commemorate Queen Victoria's Diamond Jubilee in 1897. In 1898–1901 Chester's public baths were built; this was an unusual work for Douglas as it involved specialist engineering work. During this period one of Douglas's most important secular buildings was designed, St Deiniol's Library, at Hawarden, Flintshire, for W. E. Gladstone and his family. The first phase was constructed between 1899 and 1902, and the library was completed in 1904–06. Around this time the practice was commissioned to work on two churches in association with Gladstone; St Ethelwold's (1898–1902) was a new church at Shotton in Flintshire, and additions were made to St Matthew's at Buckley, also in Flintshire, between 1897 and 1905. The other new churches built during this period were Douglas's only Scottish church, the Episcopal Church (1903) in Lockerbie, Dumfriesshire, and St Matthew's Church (1910–11) in Saltney, Flintshire. Alterations were made and furniture was designed for other churches. Douglas's last major project was the addition of a tower to his church of St Paul's at Colwyn Bay, but he died before this could be completed.
Output:
What is the name of the church that was the site of the last major project of the engineer who worked on the Chester public baths?
