We've received some snippets of information about what the Tunnel of Love will look like: It will be bookended by new, heart-shaped entrances, and five-foot tall "conversation hearts" will line the walkway. The rest of the details are still under wraps, but will be visible to all at the big party on Saturday.

Bostonians get pretty excited for Christmas tree lightings each year, so it stands to reason that our city will adore this Valentine's trellis lighting, too. After all, as enter into the depths of winter, and come off a loss in the Super Bowl, our city could use a little extra T.L.C. As curator Robyn Reed told North End Waterfront website earlier this month: "Columbus Park is gorgeous year-round, but by February, we all need some extra beauty to get us through the end of winter." Be sure to scoop up your littlest Valentines (or your special sweetheart) and take them through the Tunnel of Love before it goes away in March.
