Shamrock Hotel  The Shamrock was a hotel constructed between 1946 and 1949 by wildcatter Glenn McCarthy southwest of downtown Houston, Texas next to the Texas Medical Center. It was the largest hotel built in the United States during the 1940s. The grand opening of the Shamrock is still cited as one of the biggest social events ever held in Houston. Sold to Hilton Hotels in 1955 and operated for over three decades as the Shamrock Hilton, the facility endured financial struggles throughout its history. In 1985, Hilton Hotels donated the building to the Texas Medical Center and the structure was demolished on June 1, 1987. Designed by Fort Worth architect Wyatt C. Hedrick, the eighteen-story building with a green tile pitched roof and 1,100 rooms was conceived by McCarthy as a city-sized hotel scaled for conventions with a resort atmosphere. The hotel was located in a suburban area three miles (5 km) southwest of downtown Houston at the acute southwest corner of Main Street and Bellaire Boulevard (West Holcombe Boulevard after 1963). At the time, this was on the fringes of countryside and was meant to be the first phase of a much larger indoor shopping and entertainment complex called McCarthy Center, anchored alongside the planned Texas Medical Center. At the hotel's north side was a five-story building containing a 1,000-car garage and exhibition hall. To the south was the hotel's lavishly landscaped garden designed by Ralph Ellis Gunn, a terrace and an immense swimming pool measuring 165 (50m) by described as the world's biggest outdoor pool, which accommodated exhibition waterskiing and featured a 3 story-high diving platform with an open spiral staircase. Construction was completed for about $21,000,000 (equivalent to over $200,000,000 in 2007). Politician and entrepreneur Jesse H. Jones privately warned McCarthy that business travelers would be reluctant to stay at a hotel three miles south from downtown Houston. Hotel industry executives flatly warned McCarthy the project would not be profitable. He publicly replied, "I went into the oil business in 1933 when everybody said I was a damn fool. Now they're saying it again about my hotel." The lobby was paneled in burled mahogany with added trim heavily influenced by Art Deco, a design movement which had been popular during the 1920s and 30s. McCarthy ordered furnishings and decor in 63 shades of green, a nod to his ancestral Ireland. Hedrick's architectural firm had reportedly been the third-largest in the US, however his conservative design for the building's exterior along with its lavish interiors by Robert D. Harrell of Los Angeles drew wide criticism, notably from Frank Lloyd Wright who while being shown the completed facility before it opened, pointed at the lobby ceiling and said to Fay Jones, "That, young man, is an example of the effects of venereal disease on architecture."
