A nondescript wall near Gariahat is being transformed into a colourful canvas by a group of students.

On table tops, carrying brushes and paint, students of The BSS School, are working on a 10ft-high and 100ft-long wall of the Ballygunge tram depot outside their school campus.

The school will be celebrating its platinum jubilee in January and working on the school’s surroundings is part of the celebrations, said a school official.

Children need to be aware and conscious about their environment, said principal Sunita Sen.

“Celebration is not only about cultural programmes but about being more conscious and aware of the environment and it should begin right in their vicinity. The girls need to learn that their neighbourhood is an extension of their homes or school campuses and they have a responsibility towards it,” said Sen.

The wall will represent a coexistence of flora and fauna with paintings of trees and animals.

The girls started with stencil work last week and intend to complete it in another week. The painting began on Monday.

Working on a wall takes more time, said a student.

“It is not easy to get the shades right immediately and we have to experiment and redo it to get the required shade. The texture of a wall is different from that of a paper,” said the student of Class VI.
