Narrative:

Day VFR landing on runway 28L (new runway for fll) visual approach. At approx. 2 miles from landing I noticed a very unusual approach end to runway 28L. It seemed like a very large and tall fence at the approach end of the runway. I was concerned and asked my copilot if what I thought I saw was correct; he wasn't sure. Neither one of us had landed on this new runway before. On closer examination it become clear that it was a very tall sea wall approx. 65ft tall surrounded by sand that made it look much taller. Crossing the threshold and just starting to pull the power to idle we received a GPWS warning that both of us thought was 'glideslope' initially. Now just prior to touchdown we realized it was warning was 'terrain'. With the power now at idle; and day VFR I thought the safest course of action was to land. Of course there was no terrain ahead of the aircraft and we considered it a false warning. I think the large sea wall and the drastic vertical difference in terrain just prior to landing fooled the GPWS into the alarm. I remember several years ago on an approach plate into charleston west virginia that read 'you may receive a false GPWS warning do to terrain'. I think this is a similar condition.the runway is also sloped significantly downhill (even more so than runway 23 in clt) that may be a contributing factor.add to the approach plate that a GPWS warning may be triggered do to the 65 feet sea wall at the approach end of runway 28L.

Title: An A321 flight crew landing in VMC on Runway 28L at FLL received a GPWS Terrain warning as they crossed the threshold; closing the throttles for landing. The reporter suspects the 55 foot raised elevation at the approach end of the runway and the 'seawall' type structure supporting it contributed to a false warning.
