  We have collected archival data on NGC7673 to constrain the star-formation
history that produced the young star clusters and the field stellar population
in this galaxy during the last 2 Gyr. We have considered the sample of 50 star
clusters detected by HST/WFPC2 in the UV, V and I bands and estimated their
age, intrinsic reddening, and mass via comparison of their colours with
STARBURST99 models. We have found two prominent epochs of cluster formation
occurred about 20 Myr and 2 Myr ago, with somewhat minor events between 3 Myr
and 6 Myr ago. The star clusters are characterised by an intrinsic reddening
E(B-V) < 0.4 mag and a mass lower than 2e+06 solar masses. Out of the 50 star
clusters, we have selected 31 located within the boundaries of the IUE large
slit that was employed to obtain the spectrum of NGC7673 between 1150 Ang. and
3350 Ang. For each cluster, we have built a synthetic spectrum corresponding to
the age, mass and intrinsic reddening derived from the cluster colours,
properly redshifted to NGC7673. The spectra have then been added together in a
final, clusters integrated spectrum. This and the IUE and FUSE spectra of
NGC7673 have allowed us to describe the star-formation history of the
unresolved stars in the field as either exponentially decaying or multi-burst.
In the first case, we have derived an e-folding time of 700 (900) Myr and an
initial star-formation rate of 16 (13) solar masses per year when the
Fitzpatrick's (Calzetti's) extinction law is used. In the case of a multi-burst
star-formation history, the field population turns out to be composed by a
young (< 40 Myr) component 3 (2) times brighter than the star clusters, and a
component as old as 850 (450) Myr, about 200 (100) times more massive than the
star clusters together.
