    Request for Withdrawal of Registration Statement on Form N-2
    File Nos. 333-82967, 811-09449

Ladies and Gentlemen:

    On July 16, 1999, Nuveen Insured California Dividend Advantage Municipal
Fund (the "Registrant") filed a registration statement on Form N-2 relating to
the registration of common shares of beneficial interest of Nuveen Insured

004344).  The registration statement has been on file with the Commission for

notified the Registrant by letter dated May 22, 2000 that, pursuant to Rule 479
under the Securities Act of 1933, the registration statement would be abandoned
if the Registrant did not within 30 days file a substantive amendment, withdraw
the registration, or provide the staff a satisfactory explanation as to why
either of the previous options cannot be accomplished.

    Pursuant to Rule 477(a) under the Securities Act of 1933, the Registrant
hereby requests the withdrawal of the above mentioned Form N-2 for Nuveen
Insured California Dividend Advantage Municipal Fund.

                         Sincerely,
