Eutaw–Madison Apartment House Historic District: Eutaw–Madison Apartment House Historic District is a national historic district in Baltimore, Maryland, United States.  It consists of a group of three multi-story apartment buildings built in the first quarter of the 20th century.  They are: The Esplanade, a 9-story apartment building built in 1912; the Emersonian, an 8-story building constructed in 1915 of stuccoed masonry; and Temple Gardens, a 14-story building built in 1926.  The district is significant in part because of its association with Baltimore's Jewish community.

By the 1920s the neighborhood had been established firmly as a neighborhood of middle and upper-class Jews, many of whom were professionals and merchants.

Upper Brownlee School: The Upper Brownlee School is a historic school building located on Dry Buck Road near Sweet, Idaho, United States.  The school was built in 1911 by the residents of Brownlee, one of the several small mining communities which had grown in the Boise River basin in the late 19th century.  The two-room schoolhouse was built in keeping with contemporary standards for rural schools; it provided for heating and ventilation, had several windows to provide light, included two cloakrooms and a library room, and featured hand-carved wooden trim for decoration.  Like many rural Idaho schools, the schoolhouse also served as the local community center.  The declining local population and the expense of new safety regulations in the 1940s spelled the end of Brownlee's school, and the district merged into Sweet's district in 1951.  The building was purchased by area residents to serve as a community center and is now the only active community building in the area.
