Rauma Lace Week (pitsiviikko) is perhaps the best time to visit Rauma if you want to see something special. The usual time for Lace Week is at the end of July. You should check the dates from City of Rauma web site [14]. One of the nights is themed the Night of Black Lace (mustan pitsin yö), which starts as a cultural happening and usually degrades very quickly into a massive (on local scale) bar-crawling exercise.
