\rationale{The aim of polarimetry is to separate and investigate the nature of
the different radiation components contributing to the rest-frame total UV and
optical flux, and to provide important by-products like deep total flux images
and spectra in case of imaging-polarimetry and spectropolarimetry respectively.
Polarimetry is also an important tool for testing the of the unified model of
radio-loud AGN by searching for quasar features in the polarized spectra.
However, the faintness of HzRGs places strong limits to the range of the
feasibile observations with the 4m-class telescopes, and makes the VLT the
necessary instrument to perform detailed studies. The main issues that can be
investigated are summarized as follows :

{\bf Polarized radiation.\/ } The polarization of the {\it continuum} will be 
investigated both with deep, broad-band, multi-color imaging-polarimetry and
spatially resolved spectropolarimetry, providing spatial distributions and
spectral information on the polarized radiation. The polarization properties of
the {\it emission lines} will be  studied with high s/n spectropolarimetry. If
HzRGs are misdirected quasars, broad permitted lines are expected in the
polarized spectra (for example MgII$\lambda$2800). Higher spectral resolution
will be used for the brightest objects in order to analyse in detail the
structure of the scattered broad lines. The polarization of the narrow
forbidden
lines is equally important because it can provide constraints on the spatial
extension of the obscuring torus: the low ionization lines (eg,
[OII]$\lambda$3727) are supposed to be emitted isotropically outside the torus
(and so are unpolarized), but the highest ionization lines like [NeIV] and
[NeV]
might be partially obscured, and then show some detectable polarization.
Furthermore, for the first time, the VLT will allow us to perform imaging
polarimetry (and spectropolarimetry ?) in the near-IR ($JHK$ bands) and to
understand whether the rest-frame optical continuum is dominated by unpolarized
starlight, as is now only supposed. In summary, the combination of deep
imaging-polarimetry and spatially resolved spectropolarimetry of HzRGs (both
possible only with 8--10m-class telescopes), will provide a complete set of
information which will allow us to test the generality of the unified model, to
have geometrical constraints on the obscuring torus and to study in detail the
contribution of the polarized radiation to the alignment effect in a broad,
rest-frame
spectral range $\sim$0.1--1.0 $\mu m$. The important key for a successful
program
is the observation of a significant sample of HzRGs ($>$10 objects). It is also
highly advisable the observation of a sample of low redshift RGs ($z
\sim$0.1--0.3) in the bluest spectral region accessible from the ground in
order
to compare the properties of the polarized radiation at low and high redshifts.
Finally, a sample of high redshift radio-loud quasars with radio steep spectra
(ie, matched to those of HzRGs) should be observed in order to find and
investigate `transition' objects oriented at intermediate lines of sight
between
`radio galaxies' and `radio quasars' (expected in the unified model).

{\bf Unpolarized radiation and stellar populations.\/ } The nature and the
fractional contribution of the unpolarized UV-optical light is still poorly
known. The sum of the 4 images or spectra obtained at 4 position angles for
polarimetry provide very deep images of spectra of the total flux. The deep
images will allow us to investigate the colours and the structure of the
faintest
components, while the deep spectra will be used to search for signatures of
stellar radiation. In particular, absorption lines of O and B stars (starburst)
will be searched for in the rest-frame $<$2000~\AA (typically accessible in
HzRGs
with z$>$2), while the 4000~\AA~ break, the CaII H\&K and CN absorptions will
be
studied in the HzRGs with z around 1. In addition, the spectropolarimetric data
will provide further clues. In fact, the comparison of the EW of the broad
component in the total flux and polarized spectra is related to the fractional
contribution of the unpolarized radiation to the total flux. The observation of
the redhsifted (in the far red or near-IR) H$\beta$ emission line will also
allow the estimate of the nebular contribution to the UV continuum. Finally,
the
detailed study of $P(\lambda)$ across the 4000~\AA~ break will provide a
completely independent measure of the dilution due to the old stellar
population
unpolarized radiation.

{\bf Interstellar medium and environment.\/ } Both electrons and dust particles
are present in the ISM of HzRGs. However, the it is not clear what is the
dominant population of scatterers. The answer to this question is also
important
to provide  clues to the ISM state and its relative `ingredients'. In this
regard,
spectropolarimetry, possibly extended to the near-IR, is the most powerful
tool.
In fact, the shape of the polarized spectrum is the convolution of the
scattering efficiency of the particles with the incident spectrum. Also the
shape of $P(\lambda)$ and the intrinsic (undiluted) degree of polarization are
related to the nature of the scatterers. Moreover, the FWHM of the scattered
broad lines can provide a rather accurate way to estimate the temperature of
the
scatterers in case of electron scattering, and additional clues on the physical
state of the ionized gas. Also, the luminosity of the scattered broad lines,
together with the luminosity of the incident line, allow an estimate of the
column density of the scatterers. Finally, deep spectra and polarimetry around
2200~\AA~ will provide clues to the dust properties at high redshifts. We
have available a dust scattering model and a code for spectral deconvolution
working in the UV-optical range.

It is important to stress again that the proposed observations and studies are
not feasible with the 4m class telescopes at a sufficiently detailed level, and
that the VLT will be crucial to open new research frontiers in this field.\\

Principal modes of observation are imaging and spectropolarimetry in the
optical 
and $JHK$ spectral regions. Since the observations are all sky limited, it is
essential to use a two-beam polarimeter as provided by FORS (but not definitely
with ISAAC). For at least the spectral work, a rotatable half-wave plate is
essential to allow the use of the same slit position throughout the
polarization observations.
