The stadium was open to those who wanted to pay their respects
A two-minute silence has been held across Sheffield to remember the 96 football fans killed in the Hillsborough disaster 20 years ago.
The Liverpool supporters were crushed to death on 15 April 1989 during their team's FA Cup semi-final tie with Nottingham Forest at the stadium.
The city centre siren signalled the two-minute silence at 1506 GMT.
Victims' families, survivors and players past and present gathered at Anfield for a remembrance service.
Sheffield Wednesday FC said its staff would observe the silence.
The club did not hold a formal memorial service at Hillsborough at the request of Liverpool FC and the Hillsborough Family Support Group.
But the Hillsborough memorial on Parkside Road and the Leppings Lane end at Hillsborough was open on Wednesday for those who wanted to pay their respects at the stadium.
About 300 people gathered for a brief informal service, held by a vicar in front of the memorial, which was draped with Liverpool flags and red and white flowers.
Many of those at the ground broke down in tears as they observed the two-minute silence.
Those gathered spent time looking at the tributes, before visiting the Leppings Lane end of the stadium.
Club chairman Lee Strafford said: "The thoughts of everyone associated with Sheffield Wednesday are with the families of the 96 Liverpool fans who lost their lives on 15 April 1989.
"What happened that terrible day is something that should never be forgotten.
"The Hillsborough disaster will always be remembered for the tragic loss of so many lives and it had a profound impact on countless people and families, not only in Liverpool, Sheffield and Nottingham, but across the country and overseas as well."
The crowd will also be asked to observe a minute's silence before Sheffield Wednesday's match against Southampton on Saturday.
