During my visit I was very aware that the Lagan Rivers produces an unpleasant smell at certain times of day and I detected the smell well away from the river.

The Lagan Weir, in Belfast, Northern Ireland, crosses the River Lagan between the Queen Elizabeth Bridge and the M3 cross-harbour bridge.[ Prior to the building of the weir, the river would be subject to tidal fluctuations, and low tide would expose mudflats, which were unsightly and emitted a strong odour, particularly in the summer months. Opened in 1994, the weir was seen by the Laganside Corporation as a catalyst for its redevelopment projects and was judged to be the "centrepiece" of that effort. The weir also incorporates a footbridge.

Beside the weir is the Big Fish and the Glass Of Thrones. The Glass of Thrones walking trail along the Maritime Mile in Belfast features a unique series of stained-glass windows depicting key moments from Game of Thrones®. Baratheon window is at the Lagan Weir. House Baratheon – specifically The Red Woman Melisandre - is central here, reinforcing her significance throughout the series. You’ll see the death of both King Robert - which set in motion the War of the Five Kings - and arguably the show’s number one villain, Joffrey – depicted here. The burning fleet of The One True King Stannis during the Battle of the Blackwater also feature in this predominantly red window that represent either bloodshed or Melisandre herself.
