LASPI, Ukraine — Chased from his sumptuous villa outside the Ukrainian capital and last sighted searching for a sanctuary here on the Crimean Peninsula, Viktor F. Yanukovych, the former president, suffered a final indignity on Tuesday: The masons and electricians he had hired to build a Pharaonic seaside retreat in a historic, old-growth forest decided that he would never pay his bills and started hauling away their equipment and materials.

The mansion, still under construction but even bigger than the palatial presidential residence outside Kiev that was overrun by protesters over the weekend, had been at least two years in the making, a gargantuan folly of excess just down the Crimean coast from the former summer palace of Russia’s toppled imperial family.

The main hall has a 40-foot-high ceiling and majestic view of the Black Sea, while living quarters downstairs feature an indoor swimming pool, a big hole for a hot tub and walls thick enough to withstand an armed attack.

Instructions left on the walls by builders identify what kind of flooring was to have been laid in each room, a mix of marble and wooden parquet.
