About fifty of Clayton's buildings remain in Galveston today. Many were destroyed in the great fire of November 1885 that wiped out forty-five blocks of the city. The Galveston Pavilion built about 1881, burned down in 1883. Harmony Hall, also built about 1881, burned in 1928. The flamboyant Beach Hotel, built in 1882, burned to the ground in 1888, while Clayton watched from his bed. Sacred Heart Church was so severely damaged by the hurricane of 1900 that it had to be demolished. The Ursuline Academy in Galveston, built about 1894, was one of Clayton's largest and most important architectural design. It was demolished in 1962 after sustaining damage from the 1961 Hurricane Carla.
