Franklin Street Presbyterian Church and Parsonage: Franklin Street Presbyterian Church and Parsonage is a historic Presbyterian church located at 100 West Franklin Street at Cathedral Street, northwest corner in Baltimore, Maryland, United States.  The church is a rectangular Tudor Gothic building dedicated in 1847, with an addition in 1865.  The front features two 60 foot flanking octagonal towers are also crenelated and have louvered belfry openings and stained glass Gothic-arched windows.  The parsonage has walls of brick, heavy Tudor-Gothic window hoods, and battlements atop the roof and was built in 1857.  This church was incorporated in 1844 by a group of men from the First Presbyterian Church then located at the northwest corner of East Fayette Street and North Street (now Guilford Avenue) in downtown (later relocated in 1854 to West Madison Street and Park Avenue in Mount Vernon-Belvedere neighborhood after selling their previous third church building of 1790-95 to the Federal Government which built a U.S. Courthouse there [to 1889, replaced again 1932] dedicated in 1860 by President James Buchanan).  They felt the need for a new church in that fast-growing northern section of the city formerly "Howard's Woods" of Col. John Eager Howard's (Revolutionary War commander of the famed "Maryland Line" regiment of the Continental Army) country estate "Belvedere" (mansion located at intersection of North Calvert and East Chase Streets, razed 1875) where the Washington Monument was erected with its four surrounding park squares just two blocks from their new building.  Franklin Street Church was also located on "Cathedral Hill" in the southern part of the community bordering downtown and across the street from the old Baltimore Cathedral (Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary) erected 1806-1821 and designed by Benjamin Latrobe.  Later in 1882-1886, philanthropist Enoch Pratt founded his central library for the new Enoch Pratt Free Library then facing West Mulberry Street at Cathedral, a block south which was replaced in 1931-33 by a new central library building encompassing the entire block and now directly across Franklin Street from the F.S.P.C.  In 1973, the two historic congregations reunited to form The First and Franklin Street Presbyterian Church and was centered at the First Church site on West Madison and Park.  The Franklin Street building was used by the merged congregation for a time and then sold to a fundamentalist independent Protestant congregation and later re-sold to the present "New Unity Church Ministries".  Across Cathedral Street to the northeast was the 1820s era Greek Revival home designed by Robert Mills (who also did the Washington Monument two blocks away) which later was occupied by the original Maryland Club, an exclusive Southern-leaning dining and leisure society of gentlemen, founded 1857 that was once threatened by Massachusetts Militia Gen. Benjamin F. Butler, U.S.A. when he occupied Baltimore at the beginning of the Civil War on May 13, 1861, and fortified Federal Hill with a Fort and cannons overlooking the harbor and city, "to put a shot into it" if he spied a reputed rebel flag flying or any discontent to declared martial law.  The Club later moved to North Charles and East Eager Streets in 1892 and mansion was later replaced by the former Central Building of the Young Men's Christian Association of Central Maryland (YMCA) which was closed in the 1980s and the building renovated as the Mount Vernon Hotel and Cafe.

Wallace E. Pratt House: The Wallace E. Pratt House, also known as Ship On The Desert (sometimes hyphenated), was the residence of Wallace Pratt in what is now Guadalupe Mountains National Park in far western Texas.  Pratt, a petroleum geologist for the Humble Oil & Refining Company, had previously built the Wallace Pratt Lodge in McKittrick Canyon a couple of miles to the north in the Guadalupe Mountains.  Finding the cabin site to be remote and prone to being cut off by flooding, Pratt started construction of a new, modern residence on the east slope of the mountains.  Work on the residence started in 1941.  The house was designed by Long Island architect Newton Bevin, who lived for a time at the site with his wife, and built by contractor Ed Birdsall.  Work was stopped by World War II, but resumed in 1945 and was completed the same year.  In contrast to Pratt's rustic canyon cabin, the house, which Pratt named the Ship On The Desert, is an International Style house with horizontal lines and extensive glazing.  Only 16 ft wide and 110 ft long, the house provides broad views to the east over the plans and the west to the mountains.  The majority of the house is on a single level, with a "captain's bridge" over the dining room giving access to a rooftop terrace.  A detached garage contained a guest bedroom.  Apart from glass, the predominant material was local limestone in several shades.
