A Courtyard by Marriott is planned for downtown Baton Rouge.

Marriott spokeswoman Nina Herrera-Davila said Friday that the hotel will have an estimated 147 rooms and be owned by developer Windsor Aughtry.

Meanwhile, a list of locations on hotel management company Hospitality America Inc.’s website includes a downtown Courtyard by Marriott, scheduled in 2016.

Representatives of Nashville, Tennessee-based Hospitality America and Windsor Aughtry, based in Greenville, South Carolina, are headlining a downtown development announcement set for 11 a.m. Monday at 260 Third Street, a parking lot and former location of a hotel.

Mayor-President Kip Holden and Downtown Development District officials also are scheduled to be on hand.

The event announcement contains few details, and officials did not respond to requests for information about the nature of the announcement.

The site for Monday’s announcement is owned by Third Street Acquisition LLC, according to records at the East Baton Rouge Clerk of Court’s Office. Tom Adamek and Gordon LeBlanc Jr., partners in Stonehenge Capital, own Third Street Acquisition.

Windsor Aughtry developed the Hampton Inn & Suites in downtown Baton Rouge. Hospitality America is the Hampton Inn’s management company. That deal also involved property owned by LeBlanc.

260 Third St. was formerly the site of the Istrouma Hotel. The hotel was demolished in March 1969, eight years after closing. Capitol Bank and Trust Co. bought the hotel in 1966 with plans for a new multistory bank building. But those plans were abandoned, and the site became a parking lot.
