  The moduli space of Gieseker vector bundles is a compactification of moduli
of vector bundles on a nodal curve. This moduli space has only normal crossing
singularity and it provides a flat degeneration. We prove a Torelli type
theorem for a nodal curve using the moduli space of stable Gieseker vector
bundles of fixed rank (strictly greater than $1$) and fixed degree such that
rank and degree are co-prime.
