Louth was at one time a major trading centre in the 1770s due to the canal being built. The canal costing £28,000 and ended up being the main passage for the town, this added to the wealth generation from the wool trade.

From Louth sailing s to Hull, London and other local ports run frequent services.

In 1929 the River Tetney and the canal flooded. This killed 23 people and it ruined great areas of Louth. Due to this disaster and the decrease in use of the canal made it close in 1924. And was replaced with the railway. Although today you cant navigate the canal the towpaths have been restored making it a fine walk.

The restaurant and public meeting point at the end of the canal is a great place for an amazing display of the canal. The restaurant used to be the old wool warehouse in the 18th century.

Louth is the home of some historic buildings with St James Church, and its 300-foot tower standing over the town being the most famous in the area. Others are many coaching inns and fine houses in Upgate and Westgate.

As the town is on the Greenwich meridian a small plaque marks the line in Eastgate.
