How many years did it take to build the legislative?

Answer 1

The construction of the U.S. Capitol building began in 1793 and was largely completed by 1814, although it underwent several expansions and renovations over the years. The main structure took about 21 years to build, but the Capitol has continued to evolve, with significant additions like the dome completed in 1866. Thus, while the initial building process took a couple of decades, the legislative structure has been an ongoing project since its inception.
