'Iolani Palace on Friday announced it will be open for tours an additional day each week to meet growing demand.

The palace now will be open on Mondays, in addition to Tuesdays through Saturdays.

It will continue to be closed on Sundays except for Kama'aina Sundays on the first Sunday of the month, when admission is free for those with a valid state ID.

A record 80,362 people visited 'Iolani Palace last year, a 4.5 percent increase over 2008.

Palace officials said last year's ticket revenue of more than $930,000 was the highest since the historic landmark reopened for public tours in 1978.
