On the second floor of the Harborland "Mosaic," there is a blue Christmas tree called "Marine" located in the Seaside Plaza on the 2nd floor of the Mosaic and lit up from sunset to 24:15 until December 25th. The tree stands 6 meters high and has approximately 10,000 blue LEDS decorating it. The sight of the vivid blue color shining against the background of the bright red Port Tower is especially romantic.
