Former president Mahinda Rajapakse ordered the state-of-the-art facilities built in his southern home town of Hambantota in extensive efforts to turn his rural constituency into a regional business hub.
Vast revenues were channelled into the vanity projects, mostly named after the former strongman who ruled the tropical island for a decade and was determined to keep the loss-making ventures open.
But Rajapakse's defeat at elections last month, partly due to corruption and cronyism charges, has saddled the new government with loans of close to a billion dollars and, as yet, no clear strategy to repay them.
"We will have to repay the loans for a long time, but we can't expect any tangible return from them," he told AFP.

Opened in 2013 after loans of $210 million, the Rajapakse International airport services just one airline, budget carrier flydubai.
The arrivals hall is eerily empty and the new government has ordered the terminal's air conditioning units and decorative water fountains switched off after the carrier's handful of daily passengers trickle through.
National carrier SriLankan Airlines, under orders by Rajapakse to land there, halted flights immediately after he was defeated at the January 8 polls by new President Maithripala Sirisena. The airline estimates savings of $18 million annually from the stoppage.
"The challenge for me is to energise this place," airport chief executive Derick Karunaratne told AFP.
"Just because there is an airport, airlines don't fly in. They want a destination and we are yet to build it," he said.
Located some 250 kilometres (180 miles) southeast of the capital Colombo, the town of Hambantota is an arid outpost, surrounded by farm land. But Rajapakse spent lavishly on the projects anyway, ignoring feasibility studies against the move and environmental warnings about building in an area home to elephants, leopards and bears.
