The Hamlet changed drastically and quickly in the early 20th century, but things began to slow after Theodore Roosevelt's presidency came to an end in 1909. His impact, however, would continue to shape Oyster Bay for years to come, even after his passing.The period following Theodore Roosevelt's death in 1919 was marked by a wave of improvements throughout the Hamlet, some with the intention to memorialize him, others with the desire to improve the quality or character of the downtown, and in many cases both. There were building improvements throughout the downtown, the renovation of Christ Church in 1925, and the dedication of Theodore Roosevelt Memorial Park in 1928, to name a few.————————————————Oyster Bay was also chosen as the seat of government for all of the Town of Oyster Bay, spanning from the north shore to the south and encompassing 36 villages and hamlets, in 1930. The Town Clerk's office, built in 1902, was greatly expanded on, adding a second story and a mirrored wing to the north. Town Hall has since expanded with the acquisition of the old Lyric Theater in 1973, which was renovated to serve as additional governmental offices.————————————————Other cosmetic changes came through the Works Progress Administration during the Great Depression. A new U.S. Post Office was constructed in 1936. The structure was designed to look like the newly expanded Town Hall on the opposite side of the public park. The post office was decorated with four sculptures by the Italian-born sculptor Leo Lentelli, and features six murals depicting Oyster Bay history from 1653 to 1936.
