English: Built in 1905-1907, the Beaux Arts-style Cleveland Trust Company Building was designed by George B. Post as one of his last commissions prior to his death in 1913, stands at the corner of Euclid Avenue and East 9th Street in Downtown Cleveland. At the time of its completion, the building was the third-largest Bank Building in the United States, and was the largest bank building in Cleveland, and the first building built in the city for sole occupancy by a bank. The building was constructed for the Cleveland Trust Company, founded in 1894, which merged with the Western Reserve Trust Company in 1903, and subsequently outgrew its original offices. The bank continued to grow throughout the early-to-mid-20th Century, merging with various other banks around Cleveland, and being one of the first banks in Northeast Ohio to have branch locations. The historic Cleveland Trust Building is clad in white granite with a rusticated base featuring large arched bays with keystones and bronze doors and window frames, with corinthian porticoes at the central bays of the west and north facades along the two street frontages, which are topped by pediments featuring decorative friezes, with ornate sculptural reliefs, a small two-column portico at the building’s chamfered corner facing the intersection of the two streets, windows on the second and third floors featuring recessed metal spandrel panels, a cornice with modillions and dentils, a balustrade on the parapet, and a drum and dome atop the roof over the interior rotunda. The nearly excessive ornateness and quantity of the decorative sculptural reliefs, ornament, and friezes on the exterior facade, when compounded with George B. Post’s Beaux Arts background and design philosophy, places the building into the Beaux Arts style of architecture, despite having many similarities to the Renaissance Revival and Classical Revival styles, which have been attributed to the building by architects and architectural historians in the past. Inside, the building features a four-story rotunda below a large stained glass dome, crafted by the famous Nicola D'Ascenzo, with several murals, known collectively as "The Development of Civilization in America,” which ring the top of the third floor balcony. The murals, dome, columns, arches, cornice, and stone floor of the four-story banking hall remain intact, gracing one of the most impressive rotundas in the state of Ohio, and one of the most impressive rotundas of any building designed by Post, comparable to the scale and details to another late Post design, the Wisconsin State Capitol, with the Cleveland Trust Company Building being one of his best-preserved commissions. The rest of the interior was altered in the 1970s, but has been partially restored, including original staircases, elevator screens, and balcony railings, though other areas of the interior, including ceilings and offices in areas outside the rotunda, were heavily altered during the renovation, and were not restored during the most recent round of renovations.

In 1908-1910, the 13-story Swetland Building was built to the east along Euclid Avenue, and was designed by Searles, Hirsh & Gavin in the Classical Revival and Chicago School style. Complimenting its earlier neighbor, the taller structure is simpler in appearance, with a buff brick and terra cotta facade, three-over-three and one-over-one double-hung windows, a similar cornice featuring modillions and dentils, a terra cotta-clad base with Chicago windows and large street-level openings, and light wells on the east and west facades. In 1919, a tower was proposed to be built atop the structure, but was never constructed, which helped to preserve the building's original appearance and configuration until the 1970s, and prevented the loss of the grand stained glass dome and rotunda, which would have been heavily altered or removed to accommodate the structure for the additional floors. In 1968-1971, the Marcel Breuer-designed 29-story Brutalist building, known as the Cleveland Trust Tower, was constructed immediately to the south of the original building along East 9th Street. When it was completed, it towered over the original structure, dwarfing it with its massive scale, and featured a facade clad in dark concrete panels, with a grid of concrete-framed punched window openings on the upper floors, and relatively simple, unadorned facades at the top and bottom of the structure, with wide and tall openings on the ground floor. During the next two years, the original building was renovated and heavily altered on the interior in response to the addition of the new office tower, leaving only its most significant features intact. A second wing of the tower was planned at one point to mirror the constructed tower, but wrapping the east side of the original Cleveland Trust building, which would have led to the demolition of the Swetland Building. However, these plans were never carried out, in large part due to the economic and demographic decline of Northeast Ohio that began during the 1970s.

The building was listed on the National Register of Historic Places in 1973. The building remained in use by the Cleveland Trust Company until 1991, when the Cleveland Trust Company merged with Society National Bank. This was followed by an acquisition by Key Bank in 1993, which no longer needed the structure for banking purposes, and the final offices moved out in 1996, with all operations moved to the Key Tower. The building was largely empty and closed to the public until 2005, when it was purchased by Cuyahoga County, which intended to convert the complex into a new government center, a plan which was never realized. The county government then sold the complex in 2012, and the developer has transformed the Cleveland Trust Company Building into a Heinen's Supermarket, a local chain, with offices on the upper floors. The adjacent Swetland Building also became home to part of the supermarket, with market-rate apartments on the upper floors, while the Breuer-designed Cleveland Trust Tower was converted into a hotel and apartments. Now a thriving center of activity, the complex, now known as The 9 Cleveland, is one of the many bright spots of the revitalized and vibrant Downtown Cleveland.
