were racially segregated. By the early 1890s, tennis had become popular in clubs around Baltimore and Washington, D.C., and at Howard University. An organization dedicated to developing black tennis players, the American Tennis Association held its first ATA National Championships in Druid Hill Park in August 1917. The events were men's and women's singles, and men's doubles. The practice of segregation was definitively challenged on July 11, 1948, when 24 black tennis players, protesting the city's discriminatory policies, were arrested for playing on the park's "white-only" tennis courts. The names of the protestors are commemorated on the Baltimore Tennis Club marker, located adjacent to the Rawlings Conservatory glasshouse along Druid Park Lake Drive. The incident was the subject of the last public column and editorial of the famed Baltimore editor, reporter, columnist and author, H.L. Mencken, who, writing in The Baltimore Sun in 1948, condemned the city's segregationist policies. Festivities The Druid Hill Farmers' Market is located at the Howard P. Rawlings Conservatory in Druid Hill Park. When open, it offers free programming each week, including concerts, children's activities, yoga classes, plant workshops, art workshops, hay rides, hula hoops, 4-H Workshops, and more. The market runs weekly from June through September. The Park also is the venue for the annual Charm City Cyclocross bicycle race in mid-September, which is one of the major cyclocross bicycle races on the East Coast of the United States. Since 2014 the annual Charm City Folk and Bluegrass Festival is held each April, next to the H.P. Rawlings Conservatory and Botanical Gardens. Health In 2007, the city of Baltimore spent $50,000 on exercise equipment for the park. The park consists of three workout stations around the park reservoir. The workout machines in the park are free for the public. These stations have rowing machines, elliptical, and leg presses. Many of the exercise machines are manually operated. By the end of 2010, the city of Baltimore plans to install more outdoor exercise equipment for other parks in the city. Monuments There are many different monuments in Druid Hill Park. The Wallace Monument, standing at 30 feet tall, honors fourteenth-century Scottish hero and rebellion chieftain William Wallace. The Wagner Monument, dedicated to the German composer, stands on the lawn near the Mansion House ("Druid Hill" mansion). The monument in honor of Christopher Columbus lies within a view of the main South Driveway, and looks out upon the
