After the
American Civil War Billings focused most of his energy on his architectural practice. In 1866 he was commissioned to design Cheney Hall (1869), a multipurpose recreational building for the use of the millworkers of
Manchester, Connecticut. Possibly to execute this commission, in July 1866 Joseph Billings resigned from his job at the navy yard and rejoined his brother in practice. Cheney Hall was designed primarily in the
Second Empire style with Gothic influences. They designed two office buildings in downtown Boston, the
Wesleyan Building (1870) and the second Cathedral Building (1874, demolished). In the suburbs they designed a
house for Charles Ellis (1871,
NRHP-listed) in
West Newton, the First Congregational Church (1871, demolished 2013) in
Belmont, the
Wellesley Congregational Church (1872, demolished) and the former
Thayer Public Library (1874,
NRHP-listed) in
Braintree. Also during this period, Billings designed a library (1870, demolished) for
Mount Holyoke College. The building was donated by Pauline Durant, whose husband,
Henry Fowle Durant, was a Mount Holyoke trustee. In 1870 the Durants, vocal supporters of women's education, established
Wellesley College and returned to Billings to design the new school. According to
Edward Abbott, a member of the Wellesley board of visitors, Billings considered the resulting College Hall (1875, burned 1914) to be his "chiefest work." The Durants had Billings work from the model of the
Main Building (1865) of
Vassar College, which Billings reinterpreted in a hybrid Second Empire and
High Victorian Gothic style, similar to but more elaborate than that of Cheney Hall. At its completion College Hall housed the entire institution and was soon to be functionally obsolete, as contemporary women's schools such as
Smith College were adopting more dispersed campuses similar to those of men's schools. The destruction of the building in 1914 almost forced the closure of Wellesley. Five pillars which were salvaged from the site were used in 1972 to create a memorial to the building. Billings was also known as a designer of monuments. The smaller of these included many grave markers in
Mount Auburn Cemetery for members of the Boston elite. With Gridley Bryant he won an initial competition to design the
Soldiers and Sailors Monument on the
Boston Common, on which construction was begun but was ultimately scrapped due to cost. He also designed the Civil War monument in
Concord (1867) and the pedestal for the
Equestrian statue of George Washington (1869) in the
Boston Public Garden. Billings's largest monumental work was the
National Monument to the Forefathers (1889), commemorating the
Pilgrims in
Plymouth. He submitted his proposal to the
Pilgrim Society outside of its formal competition of 1854 and in 1855 was appointed architect in place of the official winner,
Alexander Asboth. Billings employed
nativist arguments to convince the responsible committee, believing that such a work should only be designed by a "native artist." His initial design was
colossal in stature, being 153 feet tall, and was intended to "exceed any monumental structure of modern times." In 1859 cornerstones were laid for both the monument and a canopy (1867, demolished 1919) over
Plymouth Rock itself. The canopy, in the form of a
ciborum, was later replaced in part because it was felt to evoke the
Roman Catholic church, inappropriate for a New England perceived to be Protestant. In 1874 funding for the monument was not yet in hand, and in November Billings drastically reduced its size by half. Contracts were let and after his death the pedestal was completed under the supervision of his brother. The crowning statue of
Faith was placed in 1877 and was poorly received by critics. Joseph Billings's death in 1880 contributed to further delays and the completed monument was not dedicated until 1889. Billings's initial design had been widely circulated and well received in the years before the Civil War, when it was seen as a representation of the founding principles of the United States. By the time it was completed it had been outshone by the
Statue of Liberty and had been reduced to a strictly local affair. ==Personal life and death==
