Holbeach and Moulton have won top awards in the 2016 Best Kept Village and Small Towns competition.
And Swineshead and Crowland have claimed runners-up spots in the competition, organised by the Campaign for the Protection of Rural England.
Local communities are judged in four classes according to the size of the local population and a fifth class pitting past winners against each other.
In Class 3 (villages and small towns with a population of 2,501-7,000) Swineshead was runner-up to Holton Le Clay, near Grimsby.
In Class 4 (small market towns, population 2,501-7,000), Holbeach was victorious, with Crowland second.
And in Class 5 (past winners), Moulton beat Allington, near Grantham, into second place.
Class winners and runners up will be presented with their awards at a reception at Grimsthorpe Castle near Bourne at the end of the month.
