Lima has not been forgetful of the heroes of her liberty. In the beautiful Plaza de la Exposicion, at the entrance to the Paseo Colón, a handsome marble column stands to honor the memory of the other Liberator, General San Martin. It was presented to the city of Lima by a patriotic Peruvian, Colonel Lorenzo Pérez Roca. The lower terminus of the Paseo Colón, where Lima’s fashionable driveway widens at the converging of six beautiful avenues, is marked by a spacious circle, that provides an imposing site for one of the most notable monuments in South America, erected recently to commemorate the sacrifice of the glorious hero, Colonel Bolognesi, on the heights of Arica, where, having given his answer when asked to surrender—“Not till I have burned my last cartridge!”—he fell under the enemy’s fire. The monument is the work of the Spanish sculptor, Querol. It rests on steps of granite, the base being a granite block, supporting a column of white marble. Around the base are allegorical scenes, and the capital is also artistically finished in allegorical design. The statue which surmounts the column represents the hero in the act of falling, mortally wounded, with his country’s flag held close to his heart. Another handsome monument in the Paseo Colón is dedicated to Christopher Columbus, for whom the driveway is named. It is of white marble, and was designed by the Italian sculptor, Salvatore Revelli, the same model having been used for the monument in the port of Colón, Panamá. On the road to Callao, a magnificent column of Carrara marble, seventy-five feet high, and crowned by a statue of Victory, commemorates the successful defence of the port of Callao against the Spaniards on the 2d of May, 1866.
