PROBLEM: Passage: Edwin Bergstrom studied architecture at the Massachusetts Institute of Technology and at Yale University. He began his architectural practice in New York City in 1899 and then moved to Los Angeles in 1903. He partnered with John Parkinson soon after arriving in Los Angeles. After leaving the partnership with Parkinson, Bergstrom oversaw a successful solo practice. In the 1920s and 1930s, Bergstrom was associated with the Pasadena architectural firm of Bennett and Haskell. He won a design competition in 1923 to design the City of Pasadena Civic Auditorium, which anchors the south end of the city's civic center. In the late 1920s, Bergstrom was one of five prominent Los Angeles architects, organized as the Allied Architects of Los Angeles, involved in designing the Los Angeles County/USC Medical Center General Hospital (1933), an architectural monument in East Los Angeles. Bergstrom was commissioned as the chief consulting architect for the United States War Department in 1941. In this capacity, he served as the chief architect for the Pentagon in Washington, D.C. (1941–43). Bergstrom was also actively involved in the American Institute of Architects (AIA), serving as the national organization's treasurer for over 40 years and as president in 1939 and 1940. During their partnership, Parkinson & Bergstrom became the dominant architectural firm hired to design major buildings in Los Angeles. This prominent partnership designed over 25 buildings in the 10 years of their collaboration, with the majority located in the city's burgeoning downtown. Besides the Metropolitan Building, there are four other Parkinson & Bergstrom buildings located within the boundaries of the Broadway Commercial and Entertainment Historic District. As is evidenced in the Metropolitan Building, Parkinson & Bergstrom commercial buildings typically reflect influences of the Beaux Arts or Classical Revival styles popular at the turn of the century with exterior use of glazed terra cotta, decorative spandrel panels, low relief sculptural ornamentation, and large projecting cornices.

PROBLEM: Passage: William Briwere was granted the lordship of the Manor of Bridgwater by John of England in 1201, and founded Bridgwater Friary. Through Briwere's influence, King John granted three charters in 1200; for the construction of Bridgwater Castle, for the creation of a borough, and for a market. Bridgwater Castle was a substantial structure built in Old Red Sandstone, covering a site of 8 or 9 acres (32,000 to 36,000 m²). A tidal moat, up to wide in places, flowed about along the line of the modern thoroughfares of Fore Street and Castle Moat, and between Northgate and Chandos Street. The main entrance opposite the Cornhill was built with a pair of adjacent gates and drawbridges. In addition to a keep, located at the south-east corner of what is now King Square, documents show that the complex included a dungeon, chapel, stables and a bell tower. Built on the only raised ground in the town, the castle controlled the crossing of the town bridge. A thick portion of the castle wall and water gate can still be seen on West Quay, and the remains of a wall of a building that was probably built within the castle can be viewed in Queen Street. The foundations of the tower forming the north-east corner of the castle are buried beneath Homecastle House. William Briwere also founded St John's hospital which, by the time of the Dissolution of the Monasteries under Henry VIII, was worth the substantial sum of almost 121 pounds, as well as starting the construction of the town's first stone bridge. William Briwere also went on to found the Franciscan Bridgwater Friary in the town.
