Former President Jimmy Carter—who died last month at the age of 100—will be memorialized in a state funeral at the National Cathedral on Thursday, expected to be attended by all living presidents and marked by a national day of mourning.

Former President Jimmy Carter died Sunday, Dec. 29, at 100 years old. His death came just over a year after the death of his wife of 77 years, Rosalynn Carter.

Members of Congress, the Supreme Court and other dignitaries will gather at the U.S. Capitol on Tuesday for a lying-in-state ceremony for former President Jimmy Carter.
