LONDON (AP) — President Barack Obama is opening his final day in London by touring a theater dedicated to the work of playwright William Shakespeare.

Saturday is the 400th anniversary of the Bard's death, which was being observed throughout the United Kingdom.

Obama's first stop Saturday morning was the Globe theater. The theater is a replica of the circular, open-air playhouse that Shakespeare designed in 1599.

As Obama toured the theater, he spent several minutes gazing up at the structure and asking questions about the seating and performances.

He also watched a brief performance of a portion of Shakespeare's Hamlet, including the famous "To be or not to be" soliloquy.

Obama described the performance as "wonderful."
