QUES: In 1854 president Antonio López de Santa Anna enlarged the area of the Federal District almost eightfold from the original 220 to 1,700 km2 (80 to 660 sq mi), annexing the rural and mountainous areas to secure the strategic mountain passes to the south and southwest to protect the city in event of a foreign invasion. (The Mexican–American War had just been fought.) The last changes to the limits of the Federal District were made between 1898 and 1902, reducing the area to the current 1,479 km2 (571 sq mi) by adjusting the southern border with the state of Morelos. By that time, the total number of municipalities within the Federal District was twenty-two.

QUES: In 1903, Josiah White III bought a parcel of land near Ohio Avenue and the boardwalk and built the Queen Anne style Marlborough House. The hotel was a hit and, in 1905–06, he chose to expand the hotel and bought another parcel of land next door to his Marlborough House. In an effort to make his new hotel a source of conversation, White hired the architectural firm of Price and McLanahan. The firm made use of reinforced concrete, a new building material invented by Jean-Louis Lambot in 1848 (Joseph Monier received the patent in 1867). The hotel's Spanish and Moorish themes, capped off with its signature dome and chimneys, represented a step forward from other hotels that had a classically designed influence. White named the new hotel the Blenheim and merged the two hotels into the Marlborough-Blenheim. Bally's Atlantic City was later constructed at this location.
