Residents in Windermere are being asked for their views on whether they would like to see part of the town become a conservation area.
A public consultation exercise is under way and two public exhibition days have been held.
Experts say the town is worthy of being classed as a conservation area "for the quality of craftsmanship of its buildings and streets".
Residents have until 5 January to submit their views.
Full details including maps of the proposed Windermere Conservation Area boundary, a suggested management plan and an explanation of the proposed benefits of a conservation area, can be found on the Lake District National Park Authority website.
National Park Conservation and design manager David James said: "Windermere is unique in the Lake District as a settlement which developed because of the arrival of the railway during the Victorian era.
"It is distinctive for the quality of craftsmanship of its buildings and streets which give the town a special architectural and historic interest."
