Jefferson Memorial was constructed in the year ?

yes

The Thomas Jefferson Memorial Commission was created to direct the erection of a memorial to Thomas Jefferson by an Act of Congress approved in June 1934. The present-day location at the Tidal Basin was selected in 1937. The site caused considerable public criticism because it resulted in the removal of Japanese flowering cherry trees from the Tidal Basin. Further controversy surrounded the selection of the design of the Memorial. The Commission of Fine Arts objected to the pantheon design because it would compete with the Lincoln Memorial. The Thomas Jefferson Commission took the design controversy to President Franklin D. Roosevelt who preferred the pantheon design and gave his permission to proceed. On November 15, 1939, a ceremony was held in which President Roosevelt laid the cornerstone of the Memorial.

In 1941, Rudolph Evans was commissioned to sculpt the statue of Thomas Jefferson. The statue of Jefferson looks out from the interior of the Memorial toward the White House. It was intended to represent the Age of Enlightenment and Jefferson as a philosopher and statesman. The bronze statue is 19 feet tall and weighs five tons. Adolph A. Weinman's sculpture of the five members of the Declaration of Independence drafting committee submitting their report to Congress is featured on the triangular pediment. Also noteworthy, and adorning the interior of the Memorial, are five quotations taken from Jefferson's writings that illustrate the principles to which he dedicated his life.

Few major changes have been made to the Memorial since its dedication in 1943. The most important change to note is the replacement of the plaster model statue of Thomas Jefferson by the bronze statue after the World War II restrictions on the use of metals were lifted. Each year the Jefferson Memorial plays host to various ceremonies, including annual Memorial exercises, Easter Sunrise Services and the ever-popular Cherry Blossom Festival. The Jefferson Memorial is administered and maintained by the National Park Service.

The cornerstone was laid on November 15, 1939 and was officially dedicated on April 13, 1943.

It was built by Philadelphia contractor John McShain and was completed in 1943.
