Entering the twenty-first century, rapid development continued in Santiago. The Civic District was renewed with the creation of the Plaza de la Ciudadanía and construction of the Ciudad Parque Bicentenario to commemorate the bicentenary of the Republic. The development of tall buildings continues in the eastern sector, which culminated in the opening of the skyscrapers Titanium La Portada and Gran Torre Santiago in the Costanera Center complex. However, socioeconomic inequality and geosocial fragmentation remain two of the most important problems in both the city and the country.
