abstract: 'We observationally investigate star formation (SF) process occurring in AFGL 5157 (area $\sim$13.5 pc $\times$ 13.5 pc) using a multi-wavelength approach. Embedded filaments are seen in the [*Herschel*]{} column density map, and one of them is identified as an elongated filamentary feature (FF) (length $\sim$8.3 pc; mass $\sim$1170 M$_{\odot}$). Five [*Herschel*]{} clumps (M$_{clump}$ $\sim$45–300 M$_{\odot}$) are traced in the central part of FF, where an extended temperature structure (T$_{d}$ $\sim$13.5–26.5 K) is observed. In the direction of the central part of FF, the warmer region at T$_{d}$ $\sim$20–26.5 K spatially coincides with a mid-infrared (MIR) shell surrounding a previously known evolved infrared cluster. Diffuse H$\alpha$ emission is traced inside the infrared shell, suggesting the presence of massive stars in the evolved cluster. Based on the surface density analysis of young stellar objects (YSOs), embedded clusters of YSOs are traced toward the central part of FF, and are distributed around the infrared shell. Previously detected H$_{2}$O masers, H$_{2}$ knots, massive protostar candidates, and H[ii]{} region are also seen toward the embedded clusters. Using the $^{12}$CO and $^{13}$CO line data, the central part of FF is observed at the overlapping zones of two filamentary molecular clouds (length $\sim$12.5 pc) around
